[PATCH] builddeb: Fix build on non-Debian/Ubuntu distros

[Petr Vorel <petr.vorel@gmail.com>]

This fixes make bindeb-pkg for RPM based distros, which don't have
dpkg-dev (and thus not /usr/bin/dpkg-buildpackage), which sets
$DEB_RULES_REQUIRES_ROOT.

Fixes: 3e8541803624 ("builddeb: Enable rootless builds")

Hi,

I admit not many people compile kernel with bindeb-pkg on  RPM based
distro, but it'd be nice it were working.

openSUSE has most of other required packages, although there are some
missing dependencies, thus DPKG_FLAGS="-d" is needed.

Kind regards,
Petr
