Set release status flags based on info from the regressing bug 1708532

The patch as landed on bug 1708532 fixed a 2ms delay during the content process startup. It's interesting that this is causing a higher memory usage. I assume the reason here is that we still have to load the Log, and the Marionette preferences modules. All in all this is a temporary workaround until we can make use of console.createInstance()
.
Jesup, is the increase of the memory usage here fine? Note that Marionette is not enabled by default when running Firefox, and so it actually doesn't contribute to higher memory usage. Feel free to redirect the needinfo if someone else has to answer the question. Thanks.

If the memory use is only when using marionette, that's fine.

Ok, so lets leave this bug open until the usage of console.createInstance()
(bug 1712992) has been implemented.
