ical-buddy: build from source

The official tarballs don't contain any source code, just a prebuilt
i386 binary. We didn't notice since make exits 0 when the requested
targets exist even if there's no makefile.

Fixes mistydemeo/tigerbrew#41.

Stop running "prune" as part of "cleanup"

Rationale: "prune" is slow, does not need to be run as often as
"cleanup", and is potentially destructive to things like empty
directories that Homebrew did not create. Thus we should let users run
`brew prune` only when they wish to, while still being able to use `brew
cleanup`.

Closes #19863.
Remove gsutil

This is now available from PyPI, and the github tarball does not contain
all of the necessary dependencies, so remove it and recommend "pip
install gsutil".

Closes #19874.
Closes #19895.
