gl: Fall back to dlsym() if *GetProcAddress() fails
In strictly conforming EGL implementations, eglGetProcAddress() can be used
only to get extension functions, but some of the functions we want belong to
core GL(ES). If the *GetProcAddress function provided by the context fails,
try to get the address of the wanted GL function using standard system
facilities (eg dlsym() in *nix systems).
