catalogue: io.pilot.slipstream — add linux/amd64 bundle (#345)

* catalogue: io.pilot.slipstream — add linux/amd64 bundle

Only a darwin/arm64 binary was published, so slipstream failed to spawn
on any Linux host with "exec format error". Cross-compiled and signed a
linux/amd64 build with the existing publisher key (slipstream-publisher.key
in the slipstream-app repo), uploaded as a new asset on the existing
slipstream-v1.0.0 release, and added a bundles map following the
io.pilot.sixtyfour precedent (#341-area). bundle_url/bundle_sha256 stay
as darwin/arm64 for back-compat with installs on older pilotctl that
don't understand the bundles field.

Needs re-signing with the catalogue key before this takes effect —
opening for whoever holds it to review and sign.
