.gitlab-ci.d/windows: Work-around timeout and OpenGL problems of the MSYS2 jobs

The windows jobs (especially the 32-bit job) recently started to
hit the timeout limit. Bump it a little bit to ease the situation
(80 minutes is quite long already - OTOH, these jobs do not have to
wait for a job from the container stage to finish, so this should
still be OK).

Additionally, some update on the container side recently enabled
OpenGL in these jobs - but the corresponding code fails to compile.
Thus disable OpenGL here for the time being until someone figured
out the proper fix in the shader code for this.
