Enable debug logging for GRUB rescue shell options (#3581)

Browse Source 
If the system fails to boot, some kernel messages may not be shown before the
system fully boots. Enable the debug option for rescue shell options to have an
easy way to see those without modifying GRUB options. This will increase log
verbosity and turn on debug logging for Systemd as well [1].
