Disable ffprobe test internally (#900)

Summary:

Tests related to `custom_frame_mappings` that utilize ffprobe should be skipped internally as ffprobe is not available. 

In addition to adding the `pytest.skip` decorator to these tests, I removed `custom_frame_mapping` generation from `pytest.mark.parametrize` in `test_custom_frame_mappings_init_fails` to allow tests to run.
