MAHOUT-1219: LSHSearcher not always faster than BruteSearcher
The existing "benchmark" is not conclusive enough as it doesn't take into
account the adaptive nature of the JVM, doesn't run the test multiple times and
should be replaced with something more thorough.
Removing LSHSearcher from the tests for now.
