Alexander Mikhalitsyn d395d0a5d2 fuse: support idmapped ->set_acl ...

It's just a matter of adjusting a permission check condition
for S_ISGID flag. All the rest is already handled in the generic
VFS code.

Notice that this permission check is the analog of what
we have in posix_acl_update_mode() generic helper, but
fuse doesn't use this helper as on the kernel side we don't
care about ensuring that POSIX ACL and CHMOD permissions are in sync
as it is a responsibility of a userspace daemon to handle that.
For the same reason we don't have a calls to posix_acl_chmod(),
while most of other filesystem do.
