Bug 1604714 - mark flaky screen-orientation tests on ubuntu1804 webrender/asan with expectation of [OK, ERROR] r=jmaher

Changes:

Several tests in `screen-orientation` subsuite are flaky when run on ubuntu1804 with either `webrender` or `asan`. Mark them with expectation of ["OK", "ERROR"] to compensate.
