    testsuite: Fix hwasan/arguments-3.c failures
    
    This testcase had three dg-error tests for ".*<message>.*".
    But since . matches \n in Tcl regexps, the first dg-error
    ate all the output, leaving the other two to fail.
    
    The regexp is eventually embedded in a larger one, so we
    can't prefix it with (?n).  But the .*s aren't necessary,
    since dg-error tests for a partial rather than a full match.
    
    gcc/testsuite/
            * c-c++-common/hwasan/arguments-3.c: Remove extraneous .*s.
