net/frr10: update to 10.7.0

And while here, 2 other fixes added:

• Fix OSPF netmask on peer-addressed (tunnel) interfaces: advertise the peer's prefixlen instead of /32 so strict peers accept the link.
• Fix "service frr restart" leaving daemons running: with watchfrr enabled it only cycled watchfrr, not the supervised daemons. Match upstream frrinit.sh restart semantics.
