Bug 1699367 - Skip browser_ext_popup_select_in_oopif.js without Fission. r=kmag

The test basically was written for Fission, but unfortunately it fails
intermittently without Fission becasue, I assume, there was a pre-existing race
condition causing the failure without Fission, so we are going to skip the
test without Fission for now.
