Subject: [PATCH] Silence dos2unix errors

The result is that if it 1) doesn't exist, or 2) exits with error, we
don't quit making the submit file. This includes weird cases such as
permission being denied on certain directories.

It's really hard to imagine dos2unix legitimately failing, and even if
it does, the autograder should be already changing CRLF to LFs in its
test case normalization process.
