Karsten Blees 56cd5e44f4 mingw: move MSys2 specific environment tweaks to setup_windows_environment ...

Lets keep the environment initialization and conversion section as lean as
possible and move recently added tweaks to setup_windows_environment().

This fixes the following potential problems:

 * Prevent duplicate TZ variables if both TZ and MSYS2_TZ are set.
 * Some of the higher level x* APIs from wrapper.c require a working
   getenv(), using e.g. xstrdup() during initialization is dangerous.
 * Slashifying the Windows TMP variable may break native Windows programs,
   use POSIX TMPDIR instead.
 * Properly slashify TMPDIR even if it is already set, and also if we only
   have TEMP, but not TMP.
 * Reduce complexity from O(n) to O(log n).
