[Buildroot] [PATCH 1/2] package/mesa3d: Update fminf/fmaxf patch

[Bernd Kuhls]

mesa3d now ships with a pre-generated file nir_constant_expressions.c, so there
is no need to patch nir_constant_expressions.py anymore. Furthermore the
previous patch of .py forced a re-generation of the .c file during the build,
but due to missing python-mako (removed during 10.5.3 bump) this will fail.
