fixup: fix test tap-signal.tap to avoid false negatives

Problem introduced by yesterday commit v1.11-1851-g79b2c6a,
"tests: avoid yet other spurious failures on NetBSD"

* tests/tap-signal.tap: Truly ensure the exit status of the make
call under test is correctly reflected in the TAP result displayed
by the corresponding 'command_ok_' invocation.
