My GPG keys are not available inside the container, so it makes little sense to try to sign the binaries inside the container's release.sh. The solution is to split things into separate build and sign stages, with signing ocurring after the in-Docker build. Signed-off-by: Aleksa Sarai <cyphar@cyphar.com>
