configure: make it work without PKG_CHECK_MODULES

With commit c2f9b78 we added a new dependency on pkg-config for
developers which may be unwanted. This change make the configure script
still work as before if pkg-config isn't installed, it'll just use the
old zlib detection logic without pkg-config.
