patch for x11opengl memory leak

No problem if

        _this->gl_config.major_version < 3 &&
        _this->gl_config.profile_mask == 0 &&
        _this->gl_config.flags == 0

otherwise it is necessary to explicitly free the pointer returned by
glXChooseFBConfig [1].

Unluckily, there isn't a way to retrieve the fbconfig-pointer from a
GLXContext. I've attached a patch with a possible solution.

This sounds similar to a memory bug in ResidualVM.
