Avoid DNS use in test-suite, drop obsolete patches
    
    Use pre-determined buildhost in test-suite to avoid DNS usage, sometimes
    the builder DNS config is whacked which causes crazy slowdown of our builds.
    
    Drop obsolete specspo and gpg2 related patches, specspo is gone for
    seven years and gpg2 preferral is upstream in a different form (thanks
    to Igor Gnatenko for pointing these out)
