whd 499f6680a3 [netdata] fix the source address check in LeaderBase::RouteLookup() (#9335) ...

In `LeaderBase::RouteLookup()`, OT currently checks the source address
of the packet to ensure it matches any of the Prefix TLV in leader's
netdata. Actually it should also verify that the Prefix TLV has a
Border Router sub-TLV.

In the current implementation, OT may wrongly send/forward a packet to
BR when its source address matches with a Prefix TLV which only
contains an External Route sub-TLV. This lets BR accidentally forward
packets from Thread to infra network. For example, a packet from
Mesh-Local address to On-Link address will be wrongly forwarded to
infra network.

I recently noticed this problem because we're now using either
`fc00:/7` or `::/0` for external routes in netdata, which always
matches Mesh-Local source addresses and makes the issue more obvious.
