[DASH] Fix TTML text input passthrough (regression)
Note that TTML in ISO-BMFF is not supported yet. Also updated packager_test.py: - Added a test using TTML passthrough. - Computed output extension from input extension unless output_format is specified. Fixes #478. Change-Id: Ia917fc4ed3c326782791ed67601fba02ea28b11d
