Bug description:
  [Impact]

  These are needed for 20.04.4 images.

  [Test case]

  Boot a daily image, see that it still has the necessary stack
  installed and working.

  [What could go wrong]

  libdrm: adds some new api, no changes to old stuff

  llvm-13: a new package, no regression potential on it's own

  mesa: a new major release, but we'll pull the final stable release of
  21.2.x series, so there shouldn't be any regressions left at that
  point

  xserver: a new point-release, 1.20.x series is in deep maintenance
  mode, so there should be little chance of breakage
