Change subject: util: Standardize console output in the m5 writefile
command.
......................................................................
util: Standardize console output in the m5 writefile command.
When the command reports an error, it should then exit(2) and not just
return as if everything worked. When printing the number of bytes
written or the file being opened, it should write this non-error message
to cout, and not cerr.
Also used proper capitalization and punctuation in a couple messages.
