Increment HBRT EID on every commit

When HBRT first boots we read ATTR_HOSTSVC_PLID to set our starting
PLID/EID number.  However, we never increment that attribute as we
create new logs.  This will result in HBRT reusing PLIDs if it ever
reboots (e.g. after a crash or as part of a code update) and also
when it restarts after a mpipl.
