configure.ac: Add support for recent GSS-API implementations for HP-UX

By default, configure script assumes that libcurl will use the
HP-supplied GSS-API implementation which does not have krb5-config.
If a dev needs a more recent version which has that config script,
the change will allow to pass an appropriate GSSAPI_ROOT.
