EnableYumSpacewalkPlugin: rename config -> CONFIG_PATH (reserved name)

The Actor base class in leapp framework 0.18+ runs

    self.config = retrieve_config(self.config_schemas)

in __init__, which clobbers any class-level `config` attribute the actor
defined. Our class-level `config = '/etc/dnf/plugins/spacewalk.conf'` was
silently turned into the runtime config dict, so the FirstBoot phase crashed
with `TypeError: stat: path should be string, ..., not dict` on every CL
upgrade (CLOS-3960 introduced the assignment, but the rename to DEFAULT_CONFIG_PATH
in CLOS-3960's library didn't touch the actor's class attribute name).

Rename to CONFIG_PATH so the framework leaves it alone. _enable_plugin()
already silently no-ops when the file is missing, so no_auth systems
(where the spacewalk plugin is removed by rhn-client-tools >= 3.0.1)
keep skipping cleanly.

Verified live on a CL9 machine: patched actor loads,
process() reaches _enable_plugin with the string path, and silently
returns False/None when the plugin config is absent.
