python: Use console format for output of gdb.execute command

When gdb is started in MI mode, the output of gdb.execute
command is in MI-format in case when it is executed from python stop
handler while for all other cases the output is in console-format.

To assure consistent output format, this is fixed by using the console
format for all python gdb command executions.
