imx-machine-learning: use local ssd_mobilenet_v1 model

after commit 8ad093c37b we are detecting
if a model conversion fails.
Currently the mode ssd_mobilenet_v1 fails and cannot be converted by
vela.
This is reported to NXP and will be fixed in next releases.
Meanwhile, for the current version, use a local copy.

+Subject: [PATCH] use local copy of ssd_mobilenet_v1_quant model
+
+This model is broken, and the Vela conversion is failing.
+Until it is fixed, use a locally working copy.
