Fix TagFilter implementation in tag:GetResources (#3366)

The `tag_filter` method has been re-arranged to mimic the actual AWS behavior:
Return `True` if *any* tag matches a filter and *all* filters are matched.

Python's closures are late-binding, so we have to modify the lambdas accordingly!

Closes #2814
