vfs: Check attribute names in posix acl xattr handers

Browse source

The get and set operations of the POSIX ACL xattr handlers failed to check
the attribute names, so all names with "system.posix_acl_access" or
"system.posix_acl_default" as a prefix were accepted.  Reject invalid names
from now on.
