Subject: [PATCH] Ensure /etc/network exists before setting up
 /etc/network/interfaces

When grml-debootstrap is invoked with `--debopt --variant=minbase`, our
handling of /etc/network/interfaces fails, as the directory
/etc/network/ doesn't necessarily exist yet in the essential/minbase
variants (unless you explicitly install ifupdown/netbase).

Closes: #930468
