d/copyright: adapt to file moves and deletions

Lots of targeted commands consisting of a single file as source got
moved a level up from their command-specific sub-directory to cmd/
directory directly.

A handful of build-artefacts like configure/m4 files generated by
auto-tools, was removed from being tracked by git.

Then some stuff was simple unused or broken and got deleted
(vdev_cache, zfs_spa).

Others where replaced (sha256 by general sha2 library, zstreamdump by
zstream).
