    Add a better diagnostic message in mi_gdb_test
    
    When using mi_gdb_test, if it fails because of the presence of
    unexpected output, the error message is only the message passed as
    the argument with no indication that there was an unexpected output.
    This change adds an additional text to the failure message to
    indicate that there was an unexpected output.
    
    gdb/testsuite/ChangeLog:
    
    	* lib/mi-support.exp (mi_gdb_test): Add additional message
    	for unexpected output.
