net: don't wait 5 seconds to re-read /etc/resolv.conf
If a Go process starts up, finds /etc/resolv.conf empty, then the DHCP
client writes /etc/resolv.conf, the Go program would find itself
broken for up to 5 seconds.
We noticed this during integration tests in ephemeral VMs using
gokrazy that boot into our application.
