omarchy-ane-dkms: ship omarchy-ane-smoke and its runner

omarchy-ane-smoke (joshuaswarren/omarchy-ane#50) runs the add program 20
times on the ANE and checks each output against the exact fp16 sum. It
runs omarchy-ane-run from its own directory with the program in
/usr/share/omarchy-ane/fixtures.

- build(): make tools/ane-run. It links libane statically and needs only
  libc and libm at run time. libdrm is a makedepend for drm.h.
- check(): add tools/test_ane_smoke.py (stub runner, fake root, no device).
- package(): install omarchy-ane-smoke, tools/ane-run as omarchy-ane-run,
  and fixtures/h14-anec/add/program-0.anec.
