Fix up weird CRLF and LF line terminators in the same file.
See https://gitlab.common-lisp.net/cmucl/cmucl/-/merge_requests/226#note_14865. There are a few files that apparently have both CRLF and LF line terminators. We should fix these (if possible) to use just LF line termination.
The files are:
```
src/benchmarks/gabriel/bmarks.lisp
src/benchmarks/soar/default.soar
src/benchmarks/soar/soar.lisp
src/hemlock/command.lisp
src/hemlock/linimage.lisp
src/hemlock/netnews.lisp
src/hemlock/ring.lisp
src/hemlock/search1.lisp
src/hemlock/search2.lisp
src/hemlock/winimage.lisp
```
```
