Subject: [PATCH] fetchpatch: Allow to pass a postFetch attribute.

Comes in handy if we want to make additional modificiations to the
output file. While I wasn't sure whether to invoke the passed postFetch
directly before the patch or afterwards, I thought it would be better
afterwards because "postFetch of fetchpatch" at least to my intuition
would sound that after whatever "fetchpatch" does - it comes afterwards.
