netstack: allow listening to 0.0.0.0 and ::fix/listen-any-addresses

convertToFullAddr: Replace 0.0.0.0 and :: with the empty string,
which is used by Gvisor's tcpip stack to represent the unspecified
addresses.

This fixes the following errors when using an unspecified address in
a call to ListenTCP:

tnet.ListenTCP(&net.TCPAddr{IP: net.ParseIP("::"), Port: 80})
> panic: bind tcp 0.0.0.0:80: bad local address

tnet.ListenTCP(&net.TCPAddr{IP: net.ParseIP("0.0.0.0"), Port: 80})
> panic: bind tcp [::]:80: bad local address
