[OE-core] [PATCH 1/1] systemd: mark /etc as updated to avoid unnecessary services to run

[Chen Qi]

We have updated hwdb via postinstall, updated systemd users via
'systemd_create_users', so there's no need to update /etc. Mark it
as updated to avoid unnecessary services like systemd-hwdb-update.service
to run.

This would solve timeout problem on qemumips. So also remove the
timeout change for systemd-hwdb-update.service.
