tests: kern: add some porch(1)-based tty tests

[kevans]

Summary

If sysutils/porch is installed, we'll do some basic testing of tty
behavior. The existing tests primarily cover ICANON-related processing
and corner cases that have been fixed somewhat recently, but I
anticipate growing this out a bit in due time.

Could you please demo the test program (attach the kyua html report)?

Neat, I had no idea that kyua had a report-html command.

I uploaded the report here: https://people.freebsd.org/~kevans/porch-results/

archive.tar in that directory packages the directory for convenience. IMO it leaves a little bit to be desired, I would've kinda liked to see test names to attribute each result to, but maybe it does if they fail/skip.

Timing data:

Start time: No tests run
End time: No tests run
Duration: 0.000s

Hmmm.. that seems a bit suspicious. Is there a way to confirm that the tests have run somehow?

Odd. Ok, how about:

test_canon:main  ->  passed  [4.083s]
test_canon_fullbuf:main  ->  passed  [0.009s]
test_ncanon:main  ->  passed  [0.019s]
test_recanon:main  ->  passed  [0.023s]
