It is not possible for host-setools (a host package) to have a
dependency on python3, which is a target package.

However, what is possible is that when BR2_PACKAGE_PYTHON=y, the
default host Python version is Python 2.x, and therefore host-setools
gets installed for Python 2.x, but the refpolicy build uses
host-python3, so it does not find host-setools.

I think the correct fix is instead to set
HOST_SETOOLS_NEEDS_HOST_PYTHON = python3 since anyway it only works
with Python 3.x.

Antoine: any thoughts on this ?
