Subject: [PATCH] Only check for the needed dependencies.

Helpful for dropping dependencies package dependencies.
- Git only needed if there is a .git folder
- bzip2 only needed by CDVDiso
- CG/GLEW was for zerogs and ZZogl
- jpeg was for ZZogl
.
I also added that EGL_API is also for GSdx in option comment.
