[PATCH] sstatesig: Only squash dependencies for allarch packagegroups

[Richard Purdie]

The idea of squashing packagegroup dependencies was to avoid allarch 
packages rebuilding upon tune/arch changes. Now that the allarch class
inclusion is conditional, we can narrow down the packagegroup squashing
to be specifically applied to allarch recipes.
