[PATCH 8/9] pkd: add_test pkd_hello_i1 for `make test`

[Jon Simons <jon@xxxxxxxxxxxxx>]

Add an entry for a `pkd_hello_i1` test which runs one iteration
through each of the pkd algorithm combinations.

Testing done: now `make test` will run `pkd_hello -i1` which
completes in ~25 seconds on my local machine.
