GHOST/X11: link libGL for EGL to resolve OpenGL symbols

This links libGL, since libOpenGL is not installed by default on some
distributions. This is a workaround to resolve OpenGL symbols, that are
otherwise resolved via GLVND.

GHOST/X11: enable EGL

This will replace GLX with EGL for X11. GLEW does not support GLX and EGL
at the same time. Most distributions build GLEW with GLX support, so we
have to use the externally provided GLEW and build with EGL support.
This effectively sets WITH_SYSTEM_GLEW to OFF for all Linux configurations.
