There is a known issue in legacy grub. When using splashimage with
serial console, Legacy grub wont start properly. This commit is to
ensure that when serial console is used, legacy grub should not
contain splashimage. It also adds serial support to legacy grub
configuration file.

Update the systemd serial port element implementation
so that it uses udev rules. Much nicer than
hard coding ttyS0 and ttyS1.
The udev rule only adds real serial device types
(i.e. == 4). See:
define TTY_DRIVER_TYPE_SERIAL 0x0003
from include/linux/tty_driver.h.

Since we are using bash syntax in some of the element fragments,
we should make sure we use bash for all of them, so that things don't
break on systems where /bin/sh != /bin/bash.
