kernel: set HOSTPKG_CONFIG to use pkg-config-native

The 5.19 kernel introduced a variable to specify the pkg-config
command to use for host tools.

Previously to this being introduced, we needed to overrride the
standard PKG_CONFIG* variables to avoid calls to pkg-config using
the target configuration.

While we can't completely drop the PKG_CONFIG workaround, we
should introduce the new variable, and prepare to only use it
once all supported kernels are 5.19+
