convert dos eol to unix

A number of testsuite files have dos CR/LF end of line.  Fix most of
them, so that we are less likely to run into patch failures when
contributors provide patches to these files, such as:
Hunk #1 FAILED at 1 (different line endings).
My version of git, 2.51.0, does not tell you the reason whe running
"git am", just "patch does not apply".

gprofng/examples/mxv-pthreads/README.md is also converted to unix.
