This changes the format from:
sys-apps/systemd-212-r8::coreos GPL-2 LGPL-2.1 MIT public-domain
to a JSON structure:
[
{
"project": "sys-apps/systemd-212-r8::coreos",
"license": ["GPL-2", "LGPL-2.1", "MIT", "public-domain"]
}
]
We don't have to worry about the changing format because the previous
format was never published. This is designed to match the
bill-of-materials [1] format so that it can be consumed by the site.
