[OE-core] [PATCH] layer.conf: Add several allarch dependency exclusions

[Richard Purdie]

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.
