Fix endpoints data copying during Policy Table Update

Up to now, when performing Policy Table Update, the module_config part
of the policy table was not copied. The change adds copying of this
part. The code is taken from CustomSDL/sdl_panasonic/develop (dd8ade70),
with just a small fix about copying exchange_after_x_ignition_cycles.

Fixes: APPLINK-20261
