psplash: add systemd support

Make use of the recently added systemd support in psplash. The utility
psplash-systemd communicates boot progress to the splash screen. The
splash is disabled once systemd consideres the system fully booted
(progress is at 1.0). Note that this can take a while if systemd is
stuck on a failing unit.

This change adds two systemd services. One service starts psplash itself
(psplash-start.service) and the second service starts the helper utility
psplash-systemd (psplash-systemd.service). The units are written such
that psplash-systemd.service can be used indepenendenly. This is useful
when starting psplash in initramfs (not using systemd).
