Updated archivers/pbzip2 to 1.1.8
buildlink3.mk: gtk3-atk-bridge is only valid for x11
Add more test dependencies. Bump PKGREVISION.
Updated security/py-cryptography to 0.2.2nb3
Import py27-setproctitle-1.1.8 as sysutils/py-setproctitle.

The library allows a process to change its title (as displayed by
system tools such as ps and top).

Changing the title is mostly useful in multi-process systems, for
example when a master process is forked: changing the children's
title allows to identify the task each process is busy with.  The
technique is used by PostgreSQL and the OpenSSH Server for example.
+ py-setproctitle
Added sysutils/py-setproctitle version 1.1.8
Fix PLIST.
