Reason for revert:

This is causing build_package failures on chromeos.

Original issue's description:
> Do a better job at faking simple challenge signatures.
>
> By returning a signed simple challenge that can actually be parsed as SignedData, we allow callers of the FakeCryptohomeClient to extract the original data back and process it, making for better fake behavior and simpler tests.
>
> Note that the signature is purposedly not verifiable in the FakeCryptohomeClient.
>
> BUG=643245
> TEST=chromeos_unittests; unit_tests and components_unittests also pass
>
