fixup! ozone integration

Since http://165.213.202.130/gerrit/#/c/80317/ we
hit the follow ASSERT upon launch (desktop debug build
of ubrowser --mobile).

AtExitManager has to be init'ed before frame #5,
or AtExitManager could be declared as a local variable in 'main'.

In our code, the initialization happens in the lines right below
the call to OzonePlatform::InitializeForUI.
See content/app/content_main_runner.cc@Initialize.

Patch flips those lines in order to fix the ASSERT.
