configure: Fix libnfs cflags and libs

libnfs version 16 requires the gnutls library. Without specifying at
least -lgnutls, builds fail:

  LINK fio
/usr/bin/ld: /usr/lib/gcc/x86_64-redhat-linux/15/../../../../lib64/libnfs.so: undefined reference to `gnutls_certificate_set_x509_trust_dir'
/usr/bin/ld: /usr/lib/gcc/x86_64-redhat-linux/15/../../../../lib64/libnfs.so: undefined reference to `gnutls_transport_set_int2'
...

Modify the configure script to add cflags and library options for gnutls
to correctly build libnfs engine.

Also make sure that the CI install the gnutls library header files.
