ham/chirp: Update to 20200807 (switching to daily builds)

Upstream does not have release notes (or releases).

chirp now tracks upstreams "chirp-daily" pseudoreleases, labeled by
date.  The package remains "chirp"; upstream only calls it chirp-daily
due to some GNU/Linux packaging issues.

This is a huge update as 0.4.1 is from many years ago.
