01420b2db5 network/ndisc: use router lifetime as one for redirect route 
Previously, we did not set lifetime for redirect route, and redirect
routes were removed only when received a RA from the target address.
Thus, routes that redirect on-link addresses were never removed.

RFCs mention nothing about the lifetime of redirection. But the previous
implementation does not pass the IPv6 Core Conformance Tests.

This makes
- remember all received RAs and manage them by the sender address
  (previously, remembered only one with the highest preference),
- then use the router lifetime as one for redirect route,
- remove redirect route also when the router corresponds to the sender
  address is dropped (previously, considered only target address).

Note, even if we recieve a new RA, we do not update existing redirect
routes. The lifetime of the redirect route is updated only when a new
Redirect message is received.

Closes #32527.

f1f1be71fe test-network: also set custom altternative name for netdevsim interface 
Due to the bug in kernel 6.9 caused by
8debcf5832,
the net_id udev builtin does not work for netdevsim interface.
So, eni99np1 cannot be used with kernel 6.9 anymore.

Workaround for #32910.

9944629eee network/ndisc: fix verification of sender of Redirect message 
The sender must be the first-hop router of the destination. Previously,
we only accepted Redirect messages whose sender is the current default
router with the highest priority.

See RFC 4861 section 8.1 for more details.

2e73aa507b network/ndisc: do not set per-route MTU and hop limit 
Setting MTU announced in RA message to routes is problematic, as the
value may be larger than the device MTU (IFLA_MTU), and in such case the
route cannot be used.

These two properties are now set per-interface, and gracefully handled
such invalid cases. Hence not necessary to set them to each route.

Follow-up for #32195.
