ugps: start also in case device is absent

Don't bail out from init script in case the GPS device is missing.
Some modems take time to come up, and some people may use things like
'kplex' to feed ugpsd. Hence it is better to always start ugpsd
unconditionally and let procd's respawn take care of retrying.
