xlib: use _mesa_generate_mipmap() for mipmap generation, not meta
The swrast fragment program interpreter has trouble computing the
right texture LOD because it doesn't have easy access to input
derivatives. This causes the GLSL-based meta generate mipmap code
to fetch texels from the wrong mipmap level.
One possible fix would be to set the GL_TEXTURE_MIN/MAX_LOD parameters
to limit sampling from the right level. But let's just use the
_mesa_generate_mipmap() fallback since it's a lot faster than using
the fragment shader interpreter.
Fixes http://bugs.freedesktop.org/show_bug.cgi?id=54240
Note: This is a candidate for the 9.0 branch.
