Set VirtualHost ServerName to 'calamari'

Prior to commit 525606f, the debian calamari.conf had ServerName set to
'graphite', while the el6 and rhel7 calamari.conf files had it set to
'calamari'.  I'm assuming 'calamari' is preferable to 'graphite' in this
context ;)

repobuild/precise: Get libzmq3 from trusty and not from precise

libzmq3 needs to be later than the version available for precise;
just grab it from trusty, which requires excluding it from the
precise updates, and adding a trusty distribution and an update
rule for it.
