sys-process/htop: update to Haiku-supported version 2.3.0

[Low-power]

The original version 2.0.2 builds, but almost completely useless on Haiku; as it didn't contain any Haiku-specific code, but uses the unsupported skeleton code, which can't be used to view system information and process list.

This change updates sys-process/htop to my customized version, which actually works and useful for Haiku.

Has been tested on Haiku R1/beta3.

Nice! Do you plan to submit your changes to the original htop developers?

I considered this, but since for some reasons my branch (based on the original repo at https://github.com/hishamhm/htop) has severely diverged from the current upstream branch, I would rather not try to rebase over there.

But the code itself is already released free (GNU GPL), it will be good too if someone picked up the code and submit to current upstream.

I just found #1655, which should be fixed by this pull request.

I think we would prefer to keep Haiku-support patches in-tree in HaikuPorts as a patchset instead of using a forked version where it is generally possible. Can that be done instead, please?

Well, since I finished the Haiku support in my fork in an early Haiku release first, before I discovered the haikuports, the code or patch is written for the fork and therefore would not easily applying to other version.

The original repository has been archived, any reason to keep us from merging? (PS, didn't check a 32bit build so far)

EDIT Checked out a build, seems to working fine, and mouse clicks work also.
