afs: Concoct ctimes
The in-kernel afs filesystem ignores ctime because the AFS fileserver
protocol doesn't support ctimes. This, however, causes various xfstests to
fail.
Work around this by:
(1) Setting ctime to attr->ia_ctime in afs_setattr().
(2) Not ignoring ATTR_MTIME_SET, ATTR_TIMES_SET and ATTR_TOUCH settings.
(3) Setting the ctime from the server mtime when on the target file when
creating a hard link to it.
(4) Setting the ctime on directories from their revised mtimes when
renaming/moving a file.
Found by the generic/221 and generic/309 xfstests.
