Add bcachefs creation (!123)

Set the minimum file system size to 16 MiB as creating a bcachefs that
size succeeds:
    $ truncate -s $((16*1024*1024)) /tmp/disk.img
    $ bcachefs format /tmp/disk.img
    ...
    initializing new filesystem
    going read-write
    initializing freespace
    $ echo $?
    0

Where as creating a smaller file system fails for most sizes below that:
    $ rm /tmp/disk.img
    $ truncate -s $((15*1024*1024)) /tmp/disk.img
    $ bcachefs format /tmp/disk.img
    ...
    mounting version 1.6: btree_subvolume_children
    initializing new filesystem
    going read-write

    bch2_fs_initialize(): error marking superblocks ENOSPC_disk_reservation
    bch2_fs_initialize(): error ENOSPC_disk_reservation
    bch2_fs_start(): error starting filesystem ENOSPC_disk_reservation
    error opening /tmp/disk.img: ENOSPC_disk_reservation
    $ echo $?

Closes !123 - Add support for bcachefs, single device file systems only
