UCI changes breaking Strongswan

[Philip Prindeville]

The function uci_lookup() went away in UCI, and now Strongswan is broken (or at least the UCI plugin is).

It’s not clear what the equivalent replacement logic should be, using uci_lookup_next() or uci_lookup_ptr(), etc.

If one of the UCI maintainers could review and comment on:

https://github.com/openwrt/packages/pull/25353

that would be really helpful.

Thanks,
