Work on the binary test handling.
Improvements to the task-test(7) logic for finding test suites and
binaries, now appears to behave as expected and added the list method to
easily inspect which suites/binaries would be processed by a call to
`run`.
Added task-test.test to verify failures for task-test(7) yet enable all
tests to pass when running all tests.
Added and assertion for the process.lib? command.
