Starting with Fedora 36 the NetworkManager package no longer includes
ifcfg support by default. You need an additional package
"NetworkManager-initscripts-ifcfg-rh" to pull in the compatibility
plugin. Glean's support for Fedora relies on this compatibility system
so we install this package via the simple-init element package deps.
