[PATCH] debianize: set Rules-Requires-Root in debian/control

[Isaac True <itrue@emlix.com>]

Setting "Rules-Requires-Root: no" in the debian/control file avoids
unnecessarily calling fakeroot in the build environment. Packages which
require root can override the new "DEBIAN_RULES_REQUIRES_ROOT" variable
with the desired value.

This is specifically useful when using dpkg-raw, as it no longer needs
fakeroot to create the packages. This provides a considerable speedup in
some environments (e.g. systems with very high open file descriptor
limits and specific versions of fakeroot).
