[PATCH 4/7] rpm: add PACKAGECONFIG for the systemd inhibit plugin

["Ross Burton" <ross@burtonini.com>]

RPM ships a systemd inhibit plugin, that will tell systemd to inhibit a
reboot or sleep during a package upgrades.

For native RPM this is entirely useless, and for target it's only useful
if you're using systemd+logind+rpm.

This plugin uses DBus which means it depends on expat -> cmake-native ->
libarchive-native curl-native, which is quite a dependency tree to need
in early build (required to build packages via rpm-native).

It was previously forcibly disabled for native packages but the build
dependency on DBus remained.  Remove that logic and add a PACKAGECONFIG
for the plugin that is only enabled for target builds with systemd and
explicitly disabled for native/nativesdk builds.
