Description:
On Linux or Solaris, if config file provided via --defaults-file option has \r\n as EOL sequence, MTR fails to start server with the following uninformative message:

==============================================================================

TEST                                      RESULT   TIME (ms)
------------------------------------------------------------

worker[1] Using MTR_BUILD_THREAD 300, with reserved ports 13000..13009
' found in '/tmp/my_test.cnf' at lib/My/ConfigFactory.pm line 607

Only  28  of 496 completed.
mysql-test-run: *** ERROR: Not all tests completed

How to repeat:
Create a config file with Windows-like ends-of-line.
Run
perl mysql-test-run.pl <your config file> --start

Suggested fix:
Handle \r\n and \n as valid EOL symbols 
(maybe \r as well, not sure how it works on MacOS)

      Bug #54368 MTR does not recognize carriage return in --defaults-file
      Remove any leftover trailing ^M from lines read in

The message written is intended to be informative, but the start "Unexpected line '" is overwritten because the unexpected line is a CR. :-)
