Subject: qemurunner.py: Add method run_serial

The only need for the console before this patch was
to check if the target has booted. This allows to send
commands to the terminal.

This new method is based on the method with the same name
of the QemuTinyRunner class. The difference here is it will
remove the command and the prompt. The other diference is
it will send an echo $? to check if the last command was
successful.
