[Freeciv-Dev] (PR#12992) generate_packets.py srcdir/builddir fix

["Jason Short" <jdorje@xxxxxxxxxxxxxxxxxxxxx>]

<URL: http://bugs.freeciv.org/Ticket/Display.html?id=12992 >

generate_packets doesn't work with srcdir!=builddir.

This patch lets it work by running the generation directly into the
srcdir, just like is done when srcdir==builddir.  This isn't perfect but
is better than having compilation fail.
