Remove some unneeded libs & headers
Based on some hints by the automatic dependency checking in Debian packaging[0], it appears that, at least on Debian GNU/Linux, quite a few of the libs that lugaru links against are not needed.
Remove linking to those libs, and use of related unneeded headers.
-
For ogg/vorbis, it seems like libogg is not needed unless handling container metadata?
-
For opengl, there seems to be only a subset of the libs that are required. Notably the glext.h header seems to only be needed on windows for GL_GENERATE_MIPMAP, but not otherwise.
-
For zlib it seems to be unused, but removing zlib.h exposed a dependency on unistd.h which is now included directly on non-windows.
