Merge lp:~tribaal/charms/trusty/ntp/ntp-add-charmhelper-sync-trick into lp:charms/trusty/ntp

[Chris Glass]

This branch changes only the Makefile to add a more clever "sync" target, that will automagically update charmhelpers (as is standard in openstack charms).

Original inspiration: https://bazaar.launchpad.net/~james-page/charms/trusty/keystone/network-splits/view/head:/Makefile
