Worker: add test flag to enable Blender-dependent test

Browse Source 
Add a `-withBlender` CLI argument for a unit test, to aid in debugging
T99438.

Run the test with `go test ./internal/worker/find_blender/ -args -withBlender`
to actually fail when the file association with `.blend` files cannot be
found.

Note that this doesn't rely on Blender being runnable, but it does rely
on _something_ being associated with .blend files.
