[OE-core] [PATCH 1/5] init-install-testfs: add grub serial line support

[Cristian Iorga]

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.
