Subject: [PATCH] IB: use online repositories

Change the IB packaging to only embed libc, kernel and kmod packages by default
and generate repositories.conf to refer to the remote package repositories.

Introduce a new config option CONFIG_IB_STANDALONE which restores the old
behaviour of building self contained IB archives.
