#58 Add support for files and folders in /var/lib that have owner/group attributes set

This fixes the issue in rpm packages (at least when created by redline ant task) that contains files or folder in /var/lib with owner/group other than root.

Wihtout this fix, rpm file installation on RHEL/CentOS system produces error: "file /var/lib from install of <name>-<version>.<arch> conflicts with file from package filesystem-<version>.<arch>".

For example: file /var/lib from install of test-0:1.1-1.noarch conflicts with file from package filesystem-3.2-18.el7.x86_64.
