ci(nomount): ship NoMount artifact as extracted module, not zip-in-zip

The nomount-metamodule action builds a flashable NoMount-<commit>.zip,
and upload-artifact then wrapped that zip inside another zip, so
downloading the NoMount-Metamodule artifact gave a zip-in-a-zip.

Expose the extracted module directory (module.prop, bin/, ...) as a new
module_dir output, and upload that directory as the NoMount-Metamodule
artifact in both build workflows. The release job re-zips the module
directory into a flashable zip for release assets (mirroring the
AnyKernel3 step), so the shipped zip stays intact.

module_path output is kept for sha256 checksums and future consumers.
