Win32: simplify internal mingw_spawn* APIs

Browse Source 
The only public spawn function that needs to tweak the environment is
mingw_spawnvpe (called from start_command). Nevertheless, all internal
spawn* functions take an env parameter and needlessly pass the global
char **environ around. Remove the env parameter where it's not needed.

This removes the internal mingw_execve abstraction, which is no longer
needed.
