Ignore non-existent units

In systemd, if a non-existent unit is referenced by other unit, it will
be listed in ListUnits response. This commit ignores these non-existent
entries to prevent performing operations on them.

Tested:
In dropbear.socket, there is a Conflicts=dropbear.service which creates
a non-existent service entry. With this commit, it will not be added to
the service object path in /etc/srvcfg-mgr.json.
