Undo blead customization of Text-ParseWords test script

Undo blead customization of Text-ParseWords test script

The customization simply changed DOS EOLs to UNIX EOLs, dating from a time
when the intention was to get all files in blead into UNIX EOL format.
However, since then many more files have crept in with DOS EOLs (for
example, many files under cpan/Pod-Checker, cpan/Pod-Parser and
cpan/Pod-Usage have DOS EOLs in my Git workspace (on Windows) and in the
most recent perl release tarballs (5.22.1-RC3 (made from Windows) and
5.23.5 (not made from Windows AFAIK))) and they clearly do no harm, so
there is no point in trying to make all files have UNIX EOLs and keep them
that way, and therefore no point in this customization.

The GitHub PR that was referenced in Porting/Maintainers.pl has already
been closed (not merged).

There are no changes to ParseWords.t here other than the EOLs.
