[Bug 1959646] [NEW] dhcrelay does not obey -i interface option

[Jens Elkner]

Public bug reported:

If one starts dhcrelay with explicitly specifying the interfaces to
listen,it silently ignores these options and still listens on all
interfaces. This is neither what the man page says (it says, only if no
interface is given, it listen on all interfaces), nor what is needed. It
might be even considered being a security bug because dhcrelay listens
on interfaces it shouldn't. Needless filter work causes unwanted
overhead as well.

Wrt. the source package the patches/dhcrelay-listen.patch seems to be
the root cause. It makes no sense at all to me ... Please explain or
remove.
