[Buildroot] [PATCH v2 1/1] package/mesa3d: Remove libGL headers/pkgconfig when OpenGL is disabled

mesa3d defaults to --enable-opengl due to its weird configure.ac:
http://git.buildroot.net/buildroot/commit/package/mesa3d/mesa3d.mk?id=384d601d4ea2c41bb7928f756bfe88af4d38b38b

This leads to include/GL/*.h and lib/pkgconfig/gl.pc being installed to
STAGING_DIR. These files are enough for other packages to wrongly assume
that libGL.so is present, like vlc.

Fixes

v2: Instead of fixing vlc´s libGL detection let´s remove the superfluous
    files installed by mesa3d (Yann)
