Remove specific vendor blobs and the remote.

-- Specific vendor blobs should be added in your roomservice.xml under
   local_manifest and not to the default list of packages.

  * Also with the simple github.com remote there is no need to add
    remotes cause "github" remote will always default if no remote is
    expressed which means adding TheMuppetts/proprietary_vendor_samsung
    to your local_manifest would suffice.
