Make use of cros_setup_toolchains, take 2

Resubmit of If62b4f3973f02fd8e1deed35864c824a02ab0c22
This will be safe to land after

The breakage was a timing issue paired with people not always syncing
the complete tree. No changes to the CL are needed.

It is now used for:
- make_chroot (cros_sdk --bootstrap)
- update_chroot

setup_board is stripped of redundant code which was deprecated by this.

Also stripped is some usepkg logic in make_chroot, as that is now
exclusively source-only.
