ar-track-alvar: resolves #397 with update to 0.6.1

ar_track_alvar 0.5.x only support opencv2, whereas meta-oe provides
opencv3. The ar_track_alvar kinectic versions 0.6.x also support
opencv3, as pointed out in the comment of commit e82747c4 [1].

Therefore, this commit updates ar-track-alvar to version 0.6.1
to resolve #397.
