ZOOKEEPER-3953: Update hamcrest-library to version 2.2

We use a really old version of hamcrest-library where we could use a newer one (version 2.2 instead of 1.3).
Time to update it.

Author: Tamas Penzes <tamaas@cloudera.com>

Reviewers: Enrico Olivelli <eolivelli@apache.org>, Norbert Kalmar <nkalmar@apache.org>

Closes apache#1479 from tamaashu/ZOOKEEPER-3953
