gearlever-bin, bottles-bin: bundle AUR-only dependencies

gearlever-bin: ship ftputil + desktop-entry-lib inside /usr/share/gearlever
(pinned via upstream requirements.txt) instead of depending on the AUR
packages.

bottles-bin: build the fvs2 CLI (with its core library) from source and
bundle it under /usr/lib/bottles (Bottles patched to use that path), and
ship patool, pathvalidate and vkbasalt-cli in /usr/share/bottles. vkbasalt
becomes an optdepend. Installing either package now needs no AUR builds.
