Remove old DOS source files.

These are leftover files that were kept around for posterity in the
heretic/ and hexen/ directories, that contained system-specific DOS
code used in the DOS versions of the games. There's no real reason
to keep these files around any more and it's confusing having them
around: some people who have tried to compile the code have
mistakenly tried to include these files in compilation.
