[driver] For the persistent bridging PCH job action, make sure to pass a serialized diagnostics path in the PCH output directory Previously it was passing a relative filename and the invocation was creating .dia files in the source directory. If a filename is not determined for inside the PCH output directory, it fallsback to creating a temporary for the diagnostics file, similarly to the non-persistent bridging PCH job. rdar://32594291
