Four cargo builds with four target directories compiled the GTK and GStreamer bindings four times; one build with a shared target directory takes a package build from about an hour to about seven minutes. Adds the ahfail binary and /etc/pam.d/ahfail to the install, the update_check option, an AUR PKGBUILD (offline build after cargo fetch --locked) and a tag-triggered workflow that publishes it and mirrors the PKGBUILD to the tarballz index.
