Eric Sandeen 7bc5306d74 [XFS] Remove unused header files for MAC and CAP checking functionality.
xfs_mac.h and xfs_cap.h provide definitions and macros that aren't used
anywhere in XFS at all. They are left-overs from "to be implement at some
point in the future" functionality that Irix XFS has. If this
functionality ever goes into Linux, it will be provided at a different
layer, most likely through the security hooks in the kernel so we will
never need this functionality in XFS.

Patch provided by Eric Sandeen (sandeen@sandeen.net).
