ozone: Fix GN build for ozone_egl_demo, ozone_unittests

This fixes the GN build for the ui/ozone component (and tests). The
following build should work going forward:

 gn gen out_gn_ozone --args="use_ozone=true"
 ninja -C out_gn_ozone -j1000 -k50 ozone_egl_demo ozone_unittests

BUG=396316
TEST=compile & run ozone_egl_demo, ozone_unittests
TBR=darin
