fix(p2-shim): ip dns lookup mapping return

[vados-cosmonic]

resolves #1451

What's left here is to add a regression test to make sure this stays fixed/doesn't break in the future.

[EDIT] - We don't have many tests that explore socket functionality (outside of the excellent tests in p3-shim) -- so it might be worth adding a new Rust component to test the shim and call resolve-addresses to exercise this shim path:

jco/packages/preview2-shim/lib/nodejs/sockets.js

Line 138 in 9012818

static _resolveAddresses(network, name) {

Failure on MacOS is not actually related to changes here:

Other platforms are testing OK, so going to merge this now that the follow up to add a regression test has been created
