Keep the upstream project's name out of user-visible strings

The first-party application descriptions and the telemetry service name and
instrumentation scope are shown to operators, and the unpacked-application
temp directory carried the name too.

Left alone deliberately: the OAuth key-derivation contexts (renaming them
would invalidate every sealed token and client id), the migration defaults
that read an upstream installation, links to upstream's upgrade guide, the
wire-protocol identifiers, and upstream's own license and templates.
