v0.1.0-alpha.15

Fix: Remove AUR/nonexistent packages from base edition package list

This was the actual merged package list (editions/base/packages.x86_64),
not the archiso profile copy. Same fixes: wayfire -> labwc, removed
archlinux-shim, wf-panel-pi, wf-shell, bibata-cursor-theme, wlroots,
fixed ttf-inter -> inter-font.
