50_local.conf.inc: Fix agl-sota feature for rpi2

Use "+=" instead of "=" for setting IMAGE_CLASSES
in Raspberry Pi 2 template for local.conf to
prevent failure while building images with
enabled agl-sota feature. The same fix has been
already applied to the Raspberry Pi 3 template.
Unfortunately, although with this fix the build
passes successfully, rpi-sdimg image is not
created.
