Fix process spawning with static build on Windows

Browse Source 
On Windows, process spawning needs an external helper exe which is found
relatively to the glib DLL file. If glib has been built statically this
file doesn't exist anymore and reference path is not the DLL path
anymore but the current executable path.

This patch searches for the helper exe taking as starting point the
current executable path, relative 'bin', 'lib', 'glib' and 'gio' folders
and then gets one level up until the root path. If this search doesn't
give result then the helper exe is searched using the PATH variable.
