sys-devel/gcc: backport CET fix for 11; further make jobserver related fixes for all

- jobserver:
 Led to crashes during build in some cases. Note that this is a bug in the driver
 so could easily happen when using GCC to build other things too.

- CET:
  See https://gitweb.gentoo.org/proj/gcc-patches.git/commit/?id=15daf0510a5fab17cd556261d688a6618391a0c1
  for details, but went for a more conservative approach for GCC 11.

Bug: https://bugs.gentoo.org/822036
Closes: https://bugs.gentoo.org/885501
Closes: https://bugs.gentoo.org/891655
