[v9_11] use 'command' instead of 'type' to find atf-run and kyua paths

4851. [port] Support using kyua as well as atf-run to run the unit tests. [RT #46853] (cherry picked from commit ccb5678066ea0055012352df5011ce2aa44e0eb0)

add S: T: and E: log lines

3420. [bug] Address VPATH compilation issues. [RT #31879]

report R:PASS/FAIL

Add back the "| cat" so that output files don't get truncated

3145. [test] Capture output of ATF unit tests in "./atf.out" if there were any errors while running them. [RT #25527]

remove csv output so we get a more pretty, human readable output for now. Should we want to change this later, we can change it back, but robie would need to somehow handle the atf output in the first place to make csv useful. Also, put our path first, otherwise it fails on NetBSD.

cat the output as atf-report truncates stdout

use csv output format. ticker not suitable for robie

only run test if ATFBIN defined

3043. [test] Merged in the NetBSD ATF test framework (currently version 0.12) for development of future unit tests. Use configure --with-atf to build ATF internally or configure --with-atf=prefix to use an external copy. [RT #23209]
