swayosd: put the libinput unit where systemd looks The caps-lock and num-lock overlays have never worked. Fedora's SwayOSD-0.3.2 installs swayosd-libinput-backend.service into /usr/lib64/systemd/system/, systemd searches /usr/lib/systemd/system, and on Fedora /usr/lib64 is a real directory rather than a symlink. So the unit was invisible, and the preset line added on 2026-07-21 to enable it matched nothing and was ignored without a word. That is the same silent no-op this project already documented for template units in 50-alloy.preset, reached by a different route: a preset line naming a unit systemd cannot see reads exactly like the feature being broken. Copied rather than symlinked, so it survives the package moving the file. Both directions asserted first: if the unit leaves /usr/lib64, or if it starts arriving in /usr/lib, the build fails and says to drop the workaround, rather than silently installing a stale duplicate. Verified in the image: systemd-analyze verify resolves the unit only after the copy, and default.target is graphical.target, so the unit's WantedBy actually activates.
