libgtk3: ensure host version of pkg-config is used for native compilation
This already was in Eric's submission, but I removed it when committing
while cleaning up. The package infrastructure already passes the correct
pkg-config to use for cross compilation, but NOT for building native tools,
so we ended up using the target variant and got wrong libraries/headers.
