make_game.py: write nx2navi.map next to the exe, without the lifted functions.

Browse Source 
A NX2NAVI_PROFILE profile names Rips; tools/prof_report.py needs the link map to name them, and the launcher's build
wrote none. The link now writes the map and keeps its non-lifted lines (the runtime, libraries; the f_<hex> game
functions are hundreds of MiB of it) as nx2navi.map in the game folder. The link key changes once, so the next build
links again.
