rpm: disable netcf for the interface driver in rpm build on new targets

libvirt.spec currently adds a hardcoded -Dnetcf=enabled to the meson
commandline, so just setting the default in the meson.build file won't
have any effect for rpm builds - it will be overridden.

This patch changes the meson commandline in the spec file from
hardcoded -Dnetcf=enabled to %{arg_netcf}, which is itself set
according to the value of %{with_netcf}; and *that* is normally set
according to the distro release of the build target (1 for Fedora >=
34 and RHEL >= 9, 0 otherwise), but can be manually overridden by
adding "-without netcf" to the rpmbuild commandline.

Along with being used to determine what arg to pass to meson,
%{with_netcf} is also checked when deciding on whether or not to add
netcf build time / install time dependencies ("Requires: netcf-libs"
and "BuildRequires: netcf-devel")
