ugtrain: parse adaption result and set new code addr

We can do the following now:
$ ugtrain -A -P libmemhack64.so chromium-bsu64

This gets the new code address from the adaption script and sets
it in the in-memory config. The game is directly started with the
new code address.

The only missing things are:
1. adapt the stack offset as well by preloading libmemdisc64.so
2. write back the new config to disk
