  v.db.univar: Add JSON output (#2386)

* Add JSON output to db.univar.
* Add JSON from db.univar to v.db.univar.
* All formats now handled through the format option.
* Output percentiles as two lists, not a mapping.

Tests:

* Old tests fixed.
* New tests are using pytest.
* Fixed values for test obtained from the plain output, so the new JSON output is checked to fit with the original.
* The tests with computation using NumPy would fail with different tests data, i.e., using n other than 10, fails the tests.
