gspawn: Make error codes on Windows more specific

Browse Source 
A slightly modified patch originally written by Morten Welinder
<terra@gnome.org> to make the error codes returned by g_spawn_*()
functions more specific when on Windows. They are already this specific
on Linux.

Add a unit test for the ENOENT case.
