cups: fix static linking with GnuTLS

cups forgets to link against the libs found by pkg-config if it is build with
GnuTLS support.

Otherwise, static build fails with:
../cups/libcups.a(tls.o): In function `http_gnutls_create_credential':
cups-2.1.2/cups/tls-gnutls.c:762: undefined reference to `gnutls_x509_crt_init'
[..]

Patch is sent upstream.
