grub: add console=tty0 to kernel cmdline

Browse Source 
When there is only console=hvc0 (i.e. no output to emulated VGA) and
GRUB_TIMEOUT is set to 0, VM startup hangs. This may be very well some
race condition broken by either of console=tty0 or GRUB_TIMEOUT > 0, but
even in such a case, apply this as a workaround for now.
