build-style/meson: define PKG_CONFIG for host usage.

Browse source 
PKG_CONFIG environment variable should point to the pkg-config executable
to be used to fetch dependencies that use 'native: true' (indicate to build
against host libraries not cross-compiled ones)

To meet those requirements we set an absolute path to the host
pkg-config since the relative path to pkg-config is taken by the
wrapper.

This currently requires a patch that is a milestone of meson-0.48 that
was generated by the issue:
