Fix apply_src_policies when policy is applied on multiple archs

Browse Source 
Move the logic of apply_src_policy and apply_srcarch_policy into PolicyEngine.

This fixes an issue with the excuses.yaml output introduced in commit
15e5228669: only the last verdict was added to the excuse info for that
policy.
