Fix and enable media/track/opera/track/webvtt/parsing-cue-data/* tests

Fix up the tests in above directory - mainly by disabling the
"pretty-printed" diff (which makes for very verbose *-expected files
anyway - and can be enabled reasonably easy during debugging if needed.)

The 'entities' test is not enabled at this time because it (at least one
of the subtests) trigger an assert.
