Fix profile output

86a75dce incorrectly updated the method names the profiler needs to
ignore, resulting in incorrect profiler output.

This resulted in graph output including JRuby::Profiler calls and
incorrectly reported a total time of "0.00" with "100%" time spent in
every method.

Revert to the correct names, fixing the output.
