Add profiling for unit tests.

This adds a --with-profiling argument for our unit tests that writes a
reviewboard.profile file containing profile data on our test run. We can
make use of this to figure out where the slowdowns are in our test
suite.
Ran the tests and inspected profile data using RunSnakeRun.
