Document blkid command as a mandatory requirement (#753436) 

Update the README file to document the blkid command as a mandatory
requirement for GParted.  GParted will run without blkid but it is
needed to detect a number of file systems which libparted doesn't and in
a number of other situations.

Blkid is needed to detect these file systems:
    exfat
    f2fs
    ReFS
    SWRaid
    ZFS

Blkid also detects these file systems (for which GParted has simple
internal detection but libparted, mostly, doesn't detect):
    btrfs      (detected by libparted >= 3.2)
    LVM2 PV
    LUKS
    nilfs2     (detected by libparted >= 2.4)
    reiser4

Blkid is also needed for these commits:

1)  f8faee6377
    Avoid whole disk FAT being detected as MSDOS partition table (#743181)
    (with libparted 1.9.0 to 2.3 inclusive)

2)  9e5e9f5627
    Enhance file system detection to use FS_Info method - blkid
    (Detect file systems with sector sizes other than 512 bytes with
    libparted 2.2)

Other changes to the DISTRIBUTION NOTES section of the README file:
* Drop NOTE about vol_id and blkid being used to read volume labels for
  specific file systems and read the UUIDs.  Vol_id was deprecated in
  May 2009 and is not included in any currently supported distribution.
  Blkid is now mandatory.  List of optional commands at the end of the
  section seems to cover everything that is necessary.
* Indent description of optional commands at the end of the section to
  match the indentation earlier in the section.
* Line wrap the section at column 72 to match the rest of the file.

DISTRIBUTION NOTES
------------------
Gparted uses GNU libparted to detect and manipulate devices and partition
tables. Several optional packages provide additional file system support.
Optional packages include:
GParted uses GNU libparted to detect and manipulate devices and
partition tables. The blkid command is also required to detect those
file systems which libparted doesn't detect. (The blkid command should
be considered a mandatory requirement).
GParted also queries and manipulates the file systems within those
devices and partitions. When available, it uses each file system's
specific commands. The following optional file system specific packages
provide this support:
btrfs-tools
e2fsprogs
f2fs-tools
dosfstools
mtools - required to read and write FAT16/32 volume labels and UUIDs
mtools - required to read and write FAT16/32 volume labels

NOTE: * If the vol_id command is in the search PATH, it will be used
to read linux-swap, reiser4, hfs, and hfs+ file system
volume labels.
* If the blkid command is in the search path, it will be used
to read file system UUIDs and labels. It is also used for
ext4 file system detection.
blkid is part of the util-linux package and e2fsprogs
package before that.
For dmraid support, the following packages are required:
dmsetup - removes /dev/mapper entries
dmraid - lists dmraid devices and creates /dev/mapper entries
dmraid - lists dmraid devices and creates /dev/mapper
entries
For GNU/Linux distribution dmraid support, the following are required:
- kernel built with Device Mapping and Mirroring built. From menuconfig,
it is under Device Drivers -> <something> (RAID & LVM).
