fix(network-manager): always install the library plugins directory

The library plugins directory is automatically added to the initrd if either
libnm-device-plugin-team.so or libnm-settings-plugin-ifcfg-rh.so are present on
the system, but both are optional libraries, and if it does not exist, the
NetworkManager issues a warning.
