Subject: [PATCH] networking: Restore the original /etc/hosts on activation

A patch that replaced the original file with a symlink to nix store was
reverted because MacOS Network framework doesn't support symlinks for
the file.

The revert leaves the system without any /etc/hosts file at all though.
To fix this, an activation step is added to restore the original file
from .before-nix-darwin backup, if it exists.
