Add entries to `FEATURE_EXTRACTOR_MAPPING_NAMES`

Not sure if there was any reason not to add these entries in `FEATURE_EXTRACTOR_MAPPING_NAMES`.

Furthermore, without these entries, we get some test failures for the (WIP) improved pipeline tests, because we now can generate tiny models for these config classes with the corresponding tokenizer/processor. (Previously these couldn't be generated). 
The failures are because this line
https://github.com/huggingface/transformers/blob/cc3d0e1b017dbb8dcbba1eb01be77aef7bacee1a/tests/pipelines/test_pipelines_feature_extraction.py#L182
is not able to skip relevant tests for these configs/models.

**Remark: I am going to add them to `TOKENIZER_MAPPING_NAMES` too**
