added: integration tests builddeps for apt module

test/integration/roles/test_apt/tasks/apt-builddep.yml

+# test installing build-deps using netcat and quilt as test victims.
+#
+# Deps can be discovered like so (taken from ubuntu 12.04)
+# ====
+# root@localhost:~ # apt-rdepends --build-depends --follow=DEPENDS netcat
+# Reading package lists... Done
+# Building dependency tree
+# Reading state information... Done
+# netcat
+#   Build-Depends: debhelper (>= 8.0.0)
+#   Build-Depends: quilt
+# root@localhost:~ #
+# ====
+# Since many things depend on debhelper, let's just uninstall quilt, then
+# install build-dep for netcat to get it back.  build-dep doesn't have an
+# uninstall, so we don't need to test for reverse actions (eg, uninstall
+# build-dep and ensure things are clean)
+
+# uninstall quilt
