[Buildroot] [PATCH v12 4/6] package/meson: prevent python include path manipulation

[aduskett at gmail.com <aduskett@gmail.com>]

From: Adam Duskett <Aduskett@gmail.com>

From: https://github.com/openembedded/openembedded-core/blob/master/meta/recipes-devtools/meson/meson/

Meson exports a bunch of PKG_CONFIG_ variables which causes a double prefix for
the staging python include directory.
