Regression test portability: TAP

Even with successful tests on NetBSD, we had a failure message at
the end: "No plan found in TAP output"

This was caused by a white space left padded numerical variable.
Stripping the white spaces fixes the problem.

While there add SKIP_TEST for NetBSD on unspported tests so that
it does not triger a failure.
