[LTP] [PATCH v6 6/7] Add file_attr03 test

[Andrea Cervesato]

From: Andrea Cervesato <andrea.cervesato@suse.com>

Verify that `file_setattr` is correctly setting filesystems additional
attributes. We are running test on XFS only, since it's the only filesystem
currently implementing the features we need.
