gitlab-ci, build: add a wrapper for GIMP binary to Win32 CI result.

A few commands need to be performed the first time for glib to work
properly, and gdk-pixbuf loaders to be found. I add them in a wrapper
script so that it's easy to ask people to test the dev builds (even
though it's not necessary to run these commands each time, but who
cares!).
