mkfiles: add 'mk test' support

9front has several tests scattered throughout the source,
as well as more tests in an external 'regress' repository.
Many of these tests are broken, because there is no easy
way to build and track all of them.

This pulls in several tests from different sources, deletes
the broken tests, tests with missing data, and adds a single
command that can be run from the root of the src directory
to test our system.

The hope is that as we develop new code, we add more tests,
and eventually start running the tests on every commit.
