      Bug #41017 main.events_restart fails in pushbuild: "Server failed to restart"
      
      The reason of the bug was an incorrect name for the mtr-test expect file.
      
      The name was corrected in the restart macro and an error message in mtr plus
      detailed comments in the macro would serve as a good enough protection
      from the same thing happened again.
      Bug #40636 was found as a dup for the current.
modified:
  mysql-test/include/restart_mysqld.inc
  mysql-test/mysql-test-run.pl

per-file messages:
  mysql-test/include/restart_mysqld.inc
    Correcting the name of the expect file;
    extending the macro to be able to restart an arbitrary server.
  mysql-test/mysql-test-run.pl
    Adding the error msg to print if the expect file name provided by the test does not
    correspond to an existing file.
