Subject: Automatically escape dashes in interface names

Custom interface names like "eth-phone" or "eth-lte" are not uncommon,
and since they are used in pathes inside systemd units, dashes and unprintable
characters shall be escaped per unit file rules.

So replace "-" with "\x2d" in interface names.
