Correct DOS line endings.

These files were derived from CAVP, which used DOS line endings. Several
environments will automatically convert line endings and this leads to a
mismatch if strictly comparing against the offical FIPS source
distribution tarballs.

Thus convert these files to UNIX line endings, matching the rest of the
repository.
