bug: https://github.com/npm/npm/issues/3310

still not perfect though as site has symlinks, too

cf. https://github.com/orgs/community/discussions/40387

instead, use d/copyright for toplevel licence symlink

it’s an increasement in the installed-size, sure, not much though

last nail in warning the user of the google jsapi issue

as requested by lintian

also skip calling the weigh-in, as it’s also not configured atm

This reverts commit 1164450f.
