[PATCH v2] xfs: Make 'man' hard requirement for xfs/293

[Nikolay Borisov <nborisov@suse.com>]

From: Nikolay Borisov <nborsiov@suse.com>

If xfs/293 is run on a system which doesn't have 'man' installed
it will hang the due to $CAT waiting for input indefinitely. Also
create an entry for $MAN_PROG and use the cached $MANPAGE instead
of repeatedy calling $MAN_PROG --page
