layer.conf: Add several allarch dependency exclusions

These are dependencies that our allarch packages have in OE-Core that cause
those allarch packages to rebuild every time MACHINE changes.

With these changes, OE-Core allarch packages all have a common sstate
signatures and no longer rebuild.

(From OE-Core rev: 63bff90fa4fb4a95e8c79f9f8e5dd90ae1dfc69d)
