chroot: require explicit initialisation (MR 2252)

Browse source 
We currently lazily initialize the chroot's on first use, plus a few
bonus calls to init. However, there are some instances where we actually
don't want the chroot to be initialised (mostly to break recursion
loops).

Simplify the codebase by removing all of this, and just calling
pmb.chroot.init() where it's needed.

In addition, print a warning if init() is called multiple times for one
chroot. This should help us catch these instances if they crop up again.
