Draft: fix: Change guest network bridge name to the preferred one
Since TOS 6.0, preferred name for guest network bridge is 'br-guest-turris' and foris-controller already uses that name on update of guest network.
But there can be older value as leftover from migration from TOS 5 to TOS 6 ('br-guest_turris'). For more details, see turris/foris-controller/foris-controller#256 (closed)
This shall do oneshot rename 'br-guest_turris' -> 'br-guest-turris' to use the same name everywhere.
Closes: #910 (closed)
