Load glXSwapIntervalMESA/SGI using glXGetProcAddress

SDL_GL_SWAP_CONTROL is reported as unsupported under X11, even when it is.

The bug is due to (AFAICT) an implementation oversight in
video/x11/SDL_x11gl.c: it tries to load 'glXSwapIntervalMESA' or
'glXSwapIntervalSGI' dynamically from '/usr/lib/libGL.so.1', while it
should load them through 'glXGetProcAddressARB'.

The following tiny patch does just that. This allows people to make tearing-less scrolling.
