applehv: return socket path from setupAPIForwarding

When starting podman machine with applehv, this warning is printed:
WARN[0025] API socket failed ping test

This is due to a bug in applehv.setupAPIForwarding which is not
returning the path to the socket, which causes `WaitAndPingAPI` to be
called with `""` as the socket path, triggering the warning.

This commit changes setupAPIForwarding to be similar to the
implementation in the other machine implementations.

I don't know how to add a test for this, but this can be handled in
podman-machine end to end tests by making sure that there are no
warnings when running `podman machine start` with applehv.

[NO NEW TESTS NEEDED]
