Subject: qemurunner.py: Added raw mode in run_serial

Raw mode allows to send the command without sending
'echo $?' for validation; Also this doesn't remove the
command or the prompt from the output returned. In raw
mode validation is done if there is output.

This raw mode would be useful for validate the prompt
when a user logs in.

[YOCTO #8118]
