[PATCH] build/utils: Fix broken exception handling

[Richard Purdie <richard.purdie@linuxfoundation.org>]

Checking for explicit exception names is bad, we also want to be able top
rely on inheritance. Fix these checks to be part of the real except clauses
so SkipPackage is recognised as being inherited from SkipRecipe.
