tests: (lsblk) capture multi-device filesystem sysfs in mk-input.sh

Add capture of /sys/fs/btrfs/<uuid>/devices/ and
/sys/fs/bcachefs/<uuid>/dev-*/block symlinks so that dumps
generated on systems with multi-device btrfs or bcachefs
filesystems include the sysfs data needed for mount propagation
testing.

Also add a "mnt" output with KNAME,FSTYPE,MOUNTPOINT,MOUNTPOINTS
columns.
