nmcli example: modern way to install packages (#49110)

- use the generic `package` module, this way it will cover dnf and yum
- to not specify the x86_64 arch, the package manager will pull the fine
  version anyway
- with_items with package is deprecated
- libnm-qt-devel is only in Fedora 27 and 28.
