[Rpm-maint] [rpm-software-management/rpm] check UID_0_USER before we use it. (Issue #1838)

[Einsler Lee]

Now, rpm set this macro by scaning `/etc/passwd`. But if `/etc/passwd` doesn't exist, UID_0_USER will be set to "".

We encountered this problem when we build our rpm packages on obs, and found Users and Groups of many files (especially those no %attr set in spec file) are not set. After some diging, we can reproduce this problem by removing `/etc/passwd`.

So, maybe we should check UID_0_USER before we use it. i.e. If it's `\0`, we fail or set it to `root` by default.
