In Bug 206111 I removed needed reporting for 'com.apple.runningboard' from the WebContent sandbox, but did not do so for the Network process. I should have removed it from both places (and the GPU Process sandbox).

The Mac-wk2 EWS failure cannot be related, since this patch modifies two iOS sandbox files that are not built or used in the macOS port. Likewise, the win failure cannot be related.
