classes/package_rpm: set bogus locations for passwd/group files

Since https://github.com/rpm-software-management/rpm/commit/f3eaeeb7341085e1850e914350cf1f33d538320d
rpm does its own parsing of /etc/passwd and /etc/group instead of relying on getpwnam() and friends.

This has an unfortunate effect of leaking build host uid/gid values for users and groups
into the cpio header inside rpm file (where previously those were always zero).

Installation of rpm packages relies on rpm header to set files ownership, and that
is a different structure that is build from .spec information, so we can avoid host
contamination by setting the paths to something bogus.
