systemd: Suppress cpi service error message on SEL guests

Browse Source 
On SEL guests, the default configuration does not permit the
Control-Program Identifiation (CPI) data to be sent by the cpi
service, resulting in a failure message in systemctl/log output
on start of the cpi service.

This is not a failure because it is expected behavior and the
cpi service is a one-shot service whose function is already
performed when the exit code is returned. Prevent the error log
by filtering the associated exit code in systemd.
