Fix GLX on non-linux X11 systems

Browse Source 
Some parts of the GLX code is only enabled for Linux. This makes
builds on other X11 supported platforms break when GLX is found.
To fix this enable these parts of the code when Qt feature
xcb-glx-plugin is enabled. xcb-glx-plugin has to be made public
in order for QT_CONFIG(xcb_glx_plugin) to work correctly in
these parts of the code.
