AppArmor:
added global
/etc/hosts.whonix r,
/etc/resolv.conf.whonix r,
On Whonix-Workstation this file does not contain anything interesting (unless some special configuration) and Whonix-Gateway isn't supposed to have applications installed reading those files.
This works around issue "config-package-dev clashes with AppArmor profiles".
Closes #66
