Bug#290431: dhcp3-server: regexp in postinst fails with weird ifnames

[Robert Millan]

Package: dhcp3-server
Version: 3.0.1-1
Severity: important
Tags: patch

It is possible for network interface names to contain slashes (/) in their
names (e.g. /dev/net/tun).  That breaks the sed regexp in postinst.

Patch attached.
