Update Makefile to run all tests under ./cmd/... (#102)

* Update Makefile to run all tests under ./cmd/...

* Add -p1 to make test so it doesn't try to parallelize away our inline output

@beeradb pointed out that the first line of the test would try to parallelize
stuff underneath it when given a full directory tree to test. This adds -p1
flag to avoid that.
