[PATCH] xfstests: Add test case to test xfs projid32bit functionality a bit more extensively.

[Boris Ranto <ranto.boris@xxxxxxxxx>]

 The test covers several areas including enabling projid32bit functionality dynamically by xfs_admin, dumping, restoring, quota reporting and xfs_db projid values reporting.
 At the time of creation, the test hit two bugs: one for broken xfsdump/xfsrestore functionality and one for enabling projid32bit functionality with xfs_admin on a LVM device (SCRATCH_DEV must be an LVM device to hit this).
