util.termwidth: never return 0 for terminal width

Catch a case where the termwidth was being reported as 0 when I was connecting
with TLMTask instead of NSTask in OSX. This caused the progress extension to
print no progress. The termwidth should never return 0 so in case we would
return 0, simply fall back to the default termwidth below which is 80.
