Add basic support for uninstall scripts.
RPM_INSTALL_PREFIX{n} is not yet supported and upgrading a package
where an uninstall script changes may need more work to ensure the
old script doesn't get included in the merged set (when it is too
late to remove). I haven't yet tested whether this is a real problem.
