chore(users/multi): Update htop derivation for new upstream.

- htop has moved upstreams, which has been producing new releases, so
  update the derivation to pull from the new repository on GitHub.

- All of the patches I have locally have been merged upstream, so drop
  them from the depot.

- Pull from a reasonably recent git commit instead of from a numbered
  release, as the ZFS ARC stats and CPU meter columnation patches
  haven't made it into a release yet.
