 handle nil interface from net.interfacebyname

This package built and all post-build Go tests passed fully on all local builds,
Salsa CI and on Launchpad on all architectures. However, on Debian buildd it
failed randomly, apparently as the `net.InterfaceByName` function returned a nil
interface if the specified network interface is not found or available,
manifesting as a `SIGSEGV` in the `getNetworkInfo` function. Seems that if an
error occurs (indicating `inet` is nil), the `ip_addrs` slice and `mtu` variable
are initialized to their zero values, preventing the subsequent nil pointer
dereference and ensuring the code handles unavailable interfaces gracefully.

Attempt to handle this error returned by `net.InterfaceByName` to avoid tests
failing.
