Partially revert the change to the gettytab made in r198214.

By misinterpreting some data, I thought that getty wouldn't apply any
baud rate to the syscons devices, but it uses the default entry instead.
This means that the baud rate is set to 1200. This isn't too bad, except
when using canonical mode. Make it use 9600 baud by default.
