Mathieu Duponchelle 39fcc7f58f vp9enc: expose row-mt property
With recent libvpx versions, multithreading can be enabled on
a per-tile basis, instead of on a per tile-column basis.

In combination with the new tile-rows property, this allows the
encoder to make much better use of the available CPU power.

Bump minimum libvpx version to 1.7.0
