wineboot cleanup

[Shachar Shemesh <wine-patches@sun.consumer.org.il>]

Changelog
Shachar Shemesh <winecode@sun.consumer.org.il>

programs/wineboot/wineboot.c

   * Cleaned up the code (saving on chaining strings) by CDing to the
     system root directory before doing anything else.
   * Will now rename wininit.ini to wininit.bak instead of erasing it
     as before.
