[PATCH 13/16] xfstests: generic/079 and generic/277 requires chattr, not xattrs

["Theodore Ts'o" <tytso@mit.edu>]

From: Hugh Dickins <hughd@google.com>

Add a new helper, _require_chattr, which allows the test to explicitly
check to see if the file system supports a specific chattr flag, as
not all file systems support chattr +A or chattr +i, and the presence
of extended attribute support is has nothing to do with a specific
chattr flag being supported.
