convert/gnuarch: robustify cat-log retrieval
GNU Arch used to scale very poorly when revision number was
increasing. This was mostly caused by the huge amount of
cat-log it has to scan/read through to keep track of all
patches that were merged in a given revision.
In order to improve things, cat-log prunning was a common
admin task that would accelerate cat-log parsing at the expense
of unreachabe locally stored cat-logs.
However, these missing cat-logs are still available in the archive.
So try to get them from the archive as a fallback solution.
