FYI: fix PR python/13199


I'm checking this in on the trunk.

This changes the Python startup to set sys.argv.
This is needed by some Python modules.

I think it is best to set argv this way, because we don't have any
scripting support.  We may add this (the old branch has 'gdb -P'), but
in the meantime this fixes a problem.
