[DRE-maint] Bug#666642: #666642 ruby-webrobots: FTBFS: test failed

[Christian Hofstaedtler]

The test in question (test/test_webrobots.rb context "robots.txt in
the real world" do should "be parsed for major sites" do) apparently
needs a working internet connections and the tested sites in
question need to be up (and not change their configuration).

I suggest disabling this test, at least during build time.
