Upgrade JRuby to 1.7.2
- remove gems with multiple versions
- dont' use curly expansion because some shells under make dont' support
  it.
No more Java 5 support
- sys-uname also has a special require_paths in the gemspec
initialize class var to false
- disable some anonymize filter tests because JRuby doesn't support them
  (MD4 and SHA224; these are pretty uncommon too)
- disable a few more hashes because they aren't available in JRuby
OpenSSL (plus MD4 and SHA224 aren't common anyway)
