shell/screenshot: Throw error on failure

Commit da537cda43 moved the Shell.Screenshot API to GIO's async pattern,
but we never set the GError passed to the *_finish() functions and only
indicate failure by returning FALSE.

The expected behavior is to throw an error in that situation, so make sure
we do that.
