audit: add fchmodat2() to change attributes class

[ Upstream commit 4f493a6079b588cf1f04ce5ed6cdad45ab0d53dc ]

fchmodat2(), introduced in version 6.6 is currently not in the change
attribute class of audit. Calling fchmodat2() to change a file
attribute in the same fashion than chmod() or fchmodat() will bypass
audit rules such as:

-w /tmp/test -p rwa -k test_rwa

The current patch adds fchmodat2() to the change attributes class.
