Updates multicore-sys-monitor to work on Fedora (#1646)

* Updating the Network Manager imports to use the new NM library instead of the old NMClient and NetworkManager libraries.

* Making detection of which NM libraries to use more robust.

* Making the system even better by uses GIRepository information directly and not needing to spawn a bash shell. This increases the loading speed as well.
