Don't fail to build a manifest if a tarball is missing

This is guesswork because I can't test build_manifest nor do I know what is actually causing the error to begin with. My hypothesis is that when we try to find the version from the RLS tarball and the tarball is not there, then we panic. I attempt to fix this by making the version string optional, then not adding the RLS package, rename, and extension component if the version is missing.

In theory, this should fix the broken nightlies.
