Fix the sim build

Simon pointed out that the "common/" include change in gdb broke the
sim build.  The problem was that the sim was using gdb's
create-version.sh, which changed.

This patch copies create-version.sh to the sim, so that it can
generate "version.c" in a way that works in the sim build.

Tested by rebuilding.
