bitbake/fetch2: improve error formatting for fetcher errors

* The "name" argument to FuncFailed is rarely used as a name in actual
  usage within bitbake, so don't treat it as one in the output.
* Don't print URL for FetchError if it was not specified (i.e. don't
  output "Fetcher failure for URL 'None'")
* Don't include URL in "unable to fetch from any source" message since
  we supply it to FetchError and it will be printed anyway.
* Don't include URL in "checksum failed" message for the same reason
