package/meson: add upstream patch to support pkg_config_libdir
To allow meson to distinguish between pkg-config for host (= native)
and pkg-config for target (= cross), we want to be able to give a
different pkg_config_libdir for host and for target. meson already has a
'sys_root' option that sets the sysroot that is used by pkg-config, but
we also need explicit search directories for pkg-config.
Therefore, back-port an upstream patch (will be included in 0.54) that
adds this feature.
