build: configure: Silence pkg-config check for libnetfilter_conntrack

Redirect stderr output of pkg-config to config.log in order to not spam
the configure output with pkg-config errors. Instead, use the same
pkg-config commands as for the other library checks to get
libnetfilter_conntrack cflags. Additionally, use pkg-config to the the
linker flags as well.
