packaging: add Arch Linux PKGBUILD

Add an Arch Linux PKGBUILD that builds the Unix target and
QEMU-UAE plugin from the repository sources.

Install WinUAE under /opt and publish the desktop, MIME, and icon
metadata under the system locations expected by desktop environments.

Keep the source branch pointed at back-to-the-roots so testers can
build the current Unix integration branch directly.
