Implement secpolicy_vnode_setid_retain()
Don't unconditionally return 0 (i.e. retain SUID/SGID).
Test CAP_FSETID capability.
https://github.com/pjd/pjdfstest/blob/master/tests/chmod/12.t
which expects SUID/SGID to be dropped on write(2) by non-owner fails
without this. Most filesystems make this decision within VFS by using
a generic file write for fops.
