crowd: fully remove crowd from patchwork

Since we don't really need it anymore, let's drop crowd, clean
up scripts that were relying on it, and fix our tests so they
aren't trying to mock it.

Ensure that tests are working correctly with the new Person
assumption and that we are detecting Linaro involvement in
all situations.
