licensetool: embed license DB, update for more modules (#3665)

* licensescan: Embed licenses in binary

We now embed some licenses using go:embed, so we don't need to set up
a modules DB in every project. A local modules folder is still checked
first, and TODO files are still written locally to a local modules
folder.

* licensescan: Update modules

Update a bunch of licenses from different places I've been running the
licensetool.
