feat(network-manager): remove support for ifcfg-rh

This commit removes the dracut module for the NetworkManager fcfg-rh
plugin (`nm-fcfg-rh`), effectively discontinuing its support within dracut.

The `fcfg-rh` plugin for NetworkManager provides backward compatibility
with the legacy `ifcfg` network configuration format.
This format, traditionally found in `/etc/sysconfig/network-scripts/`,
was the standard method for configuring network interfaces on Red Hat-based
distributions for many years. It relies on a collection of shell-script-like
files to define network connections.

While functional for basic configurations, the `ifcfg` format has several
limitations in the context of modern networking and the capabilities of NetworkManager.

The removal of the `nm-fcfg-rh` support from dracut is a forward-looking change
that aligns with the broader trend in the Linux ecosystem to modernize network configuration.
The key reasons for this decision are as follows:

* **Deprecation by Upstream and Distributions:**
The `fcfg-rh` plugin is considered deprecated by the NetworkManager project
and major Linux distributions, such as Fedora and its derivatives.
These distributions are actively migrating users away from the legacy `ifcfg` format
in favor of the more robust `keyfile` format.

See https://networkmanager.dev/docs/api/latest/nm-settings-ifcfg-rh.html.
