v2.03 tests fail with HARNESS_OPTIONS=j5

[kentfredric]

at its simplest, it appears presently, 2 tests in the dist can't be run concurrently, because they might create/delete the same paths.

The simplest case can be exhibited by doing

prove -lvr t/test-kwalitee.t & prove -lvr t/deprecated.t

And enough repeating of that command will eventually trigger the bug.

not ok 3 - Test dist was extractable

This looks like a Module::CPANTS::Analyse problem -- it should be using a globally unique temp dir to do its work in, so parallel processes don't stomp on each other.
