ksmbd-tools: append config from /var/run/config/ for runtime shares
Dynamically created shares shouldn't be stored in the /etc/config/
because of:
1. Flash wearing
2. Risk of inconsistent state on reboots
With this change all automation/hotplug.d scripts can store runtime in
the /var/run/config/samba. It's useful e.g. for USB drives that user
wants to be automatically shared.
Also: automated scripts should never call "uci [foo] commit" as that
could flush incomplete config. This problem also gets solved.
Identical feature was added to samba36 in the OpenWrt commit
5a59e2c059866 ("samba36: append config from /var/run/config/ for runtime
shares") but wasn't ported to ksmbd until now.
