iroh works fine in the simulator with the latest stuff, but crashes on an actual iPhone for any iroh-ffi build that references a commit after 93147ac on main

The error I see:

thread 'main-runtime' panicked at 'unable to create DNS resolver: ResolveError { kind: Io(Os { code: 2, kind: NotFound, message: "No such file or directory" }) }', /Users/b5/.cargo/git/checkouts/iroh-6b78e5b19f41ff57/33cf40b/iroh-net/src/dns.rs:5:50

I've stepped through the commits, and have confirmed the issue is introduced in 93147ac, the prior commit is fine.

fix(iroh-net): dns fallback to default config
9a4933a 
On at least iOS the resolve.conf is not available, so need to fallback to a default configuration in that case.

Based on the tested approach in DeltaChat

Fixes #1436
