Fix bottle prefix and repository handling

Revert "untap: add --force switch"

uses: add --formula and --casks flags

We were previously only looking at the `cellar` value when pouring
bottles and ignoring the `prefix` and (implicit) `repository`.

Actually look at these values and set the defaults for each platform.

Also, when we're relocating to create or pour bottles when `prefix`
and `repository` are equal then skip relocating the `repository` and
always use references to the `prefix` instead.

Fixes #9453

caveats: remove ZSH FPATH logic.

cleanup: fix portable Ruby behaviour.
