Also find system default udev rules in /usr/lib/udev/rules.d (!116) 

When blanking of udev rules was first tested [1][2] and added [3] all
the distributions at the time (CentOS 6, Debian 6, Fedora 19,
openSUSE 12.2, Ubuntu 12.04 LTS) stored the system default rules in
directory /lib/udev/rules.d.  Now most distributions (CentOS Stream 9,
Debian 11, Fedora 38, Ubuntu 22.04 LTS, openSUSE Leap 15.4) store the
system default rules in directory /usr/lib/udev/rules.d.  Most of these
distributions have a merged /usr file system [4][5] so /lib is a symlink
to /usr/lib and the system default rules can still found using the
original directory.  But openSUSE 15.4 doesn't have a merged /usr so the
gparted shell wrapper doesn't find the system default rules in directory
/usr/lib/udev/rules.d and doesn't prevent auto starting of Linux
Software RAID arrays and bcache devices during a storage probe.

An extra consideration is that Alpine Linux 3.17 doesn't have a merged
/usr file system, but has both /lib/udev/rules.d and
/usr/lib/udev/rules.d directories with different rules files.  Therefore
fix this by checking for system default udev rules in both directories.
