[Buildroot] [PATCH] configs/minnowboard_max-graphical_defconfig: unbreak X11/mesa

[Peter Korsgaard <peter@korsgaard.com>]

Fixes https://gitlab.com/buildroot.org/buildroot/-/jobs/1297337965

Commit 15a2f9b819806d38a7d8172a2 (package/{mesa3d, mesa3d-headers}: bump
version to 21.0.2) marked BR2_PACKAGE_MESA3D_DRI_DRIVER_SWRAST as legacy,
but forgot to update the defconfig.  The SW rasterizer isn't really needed
with the Intel GPU, so just drop it.

In addition, X11 now needs some help with loading the modules in the correct
order, similar to how it was done for the test in commit 4a3639bad01a
(support/testing: test_glxinfo load X11 modules in the right order).
