Subject: Split libpod/network package
The `libpod/network` package should only be used on the backend and not the
client. The client used this package only for two functions so move them
into a new `pkg/network` package.
This is needed so we can put linux only code into `libpod/network`, see #9710.
[NO TESTS NEEDED]
