AW UMA: integration tests for hardware fields

No change to production logic.

This adds tests for already-implemented UMA proto fields (specifically,
the hardware.* fields). This intentionally skips fields which don't
apply to Android OS (ex. hardware.form_factor, hardare.max_dpi_*). This
also skips fields where we're not logging a meaningful value (ex.
gpu.vendor_id), since such fields are effectively empty anyway.
