[Buildroot] [PATCH v2 2/3] package/mesa3d-headers: fix install of dri.pc

[Bernd Kuhls]

Due to the switch of mesa3d to the meson build system the upstream
tarball does not include dri.pc.in anymore, it is created during the
build now:
https://cgit.freedesktop.org/mesa/mesa/tree/src/mesa/drivers/dri/meson.build?h=19.2#n93

In order to provide dri.pc we need to add a version taken from a dri-
based mesa3d build to our source repository, by doing so we can reduce
the number of sed commands.

Without this patch the build of xserver_xorg-server, switched to virtual
opengl provider, will fail:
