[imagebuilder]

	- add a helper script to generate opkg.conf, attempt to detect package architecture from packages/
	- fix package defaults when no package override is given, IB previously aggregated the defautls of all profiles
	- introduce a repositories.conf, allows using remote opkg repositories in imagebuilder
