tests: switch to minitest

Add a compatibility shim in test/helper to avoid noisy warnings with
Minitest (out-of-the-box on Ruby 2.0.0) and also Minitest 5.

Automated conversion via:
  perl -i -p -e 's,test/unit,./test/helper,g' test/test_*.rb
  perl -i -p -e 's,Test::Unit::TestCase,Testcase,g' test/test_*.rb

Yes, I prefer Perl for one-liners :P
