Use key_value to handle V4L2 field names

Extend the key_value helper with a function to retrieve the key
corresponding to a value, and use it to replace the manual
implementation of V4L2 field name lookup.

The name comparison needs to be made case-insensitive to avoid breaking
users, as yavta handles V4L2 field names in a case-insensitive way.
