CLOS-2598: Remove dead lua_cjson_handle from ClearPackageConflicts

The lua-cjson -> lua51-cjson swap on CL7 -> CL8 is now handled by a
PES Replaced event in leapp-data (cloudlinux/pes-events.json), which
makes DNF remove lua-cjson in the same transaction that installs
lua51-cjson. The actor-level file-removal helper was never wired into
process() and is no longer needed.
