psplash: ignore startup errors in psplash-systemd.service

psplash-systemd.service depends on FIFO created by psplash-start@fb0.service.
This FIFO can be removed due to signals or /dev/fb0 related errors
when psplash-start@fb0.service exits. This exit can happen
when psplash-systemd.service is being started. Thus ignore
all errors in psplash-systemd.service startup.
There are too many ways things can go wrong and all of them
leave open race conditions unless a single process handles
all of the psplash usecases including progress bar updates.
