dpkg-deb: Normalize file permissions when creating control.tar
Permissions of file in control.tar will likely be affected by a different
umask. While `dh_fixperms` already normalizes permissions for most
packages, debhelper is not used by everywhere. As there is no use cases
for having different permissions for control files than 644 or 755,
we can normalize them directly in dpkg.
This helps packages to build reproducibly when built with different umasks.
Closes: #787980
