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. Signed-off-by: Caleb Connolly <caleb@postmarketos.org>
