Subject: [PATCH] t/harness: Run APItests in parallel

This commit changes these tests to be run like the tests in t/lib, in
parallel with each other, when available.  This is the longest running
directory, and prior to this commit, on many-core systems it can be the
final thing chugging along, a test at-a-time, while the other cores are
idle.
