layers/meta-opentrons: address robot app g2d crashes (#135)

* layers/meta-opentrons: weston increases cma size

This may help with occasional CMA OOMs (see
https://opentrons.atlassian.net/browse/RQA-2353)

* layers/meta-opentrons: restart app on failure

Because otherwise it's ugly.

Closes RQA-2353
