virtme-init: correctly initialize resolv.conf under ubuntu
In recent distro (i.e., Ubuntu) resolv.conf is a symlink to
/run/systemd/resolve/stub-resolv.conf that is not visible by the guest.
This results in a failure when trying to initialize this file.
Make sure to resolve the symlink first and initialize the actual file
with an empty file before trying to rewrite its content.
