init-install-testfs: add grub serial line support

For automated hardware testing, boot process control
via serial interface is needed. As such, in grub, serial
line support is added upon testmaster image install.

Also add a specific timeout to automatically start
the master image upon start of testing phase.

Tested on multiple hardware targets without issues.
