[PATCH 2/4] classes/package_rpm: write file permissions and ownership explicitly into .spec

[Alexander Kanavin <alex.kanavin@gmail.com>]

Per https://github.com/rpm-software-management/rpm/commit/77d3529c31ca090a40b8d3959a0bcdd721a556d6
rpm 4.19.1+ will not consider actual filesystem permissions and ownership, and will quietly default
to root if not expictly set otherwise in .spec file.
