If more than one test would use it makes sense to add a library support
for mounting debugfs.

Also generally distributions are moving into not mounting debugfs by
default, since there have been security implications of exporting
internal kernel state by default. So it would make sense to add
.needs_debugfs flag to the tst_test struct that would cause the library
mount (and later umount) debugfs at .mntpoint unconditionally.
