largefiles: simplify iteration over standins
Instead of iterating over all files in the context and ignoring those
that are not standins, pass a standin-matcher to the context and
iterate over only the files matching.
Apart from making the intent clearer, this implementation will also
benefit from any future optimizations done to the manifest walking
code.
