tests: avoid yet other spurious failures on NetBSD

* tests/tap-signal.tap: Add a "strategically placed" extra 'echo'
command and a temporary silencing of xtraces; they are required
to avoid possible garbled output with NetBSD make, which would
miss some final newlines in the expected places and thus mess up
our TAP output.
