Suse (SLES/openSUSE) support in sensu-build

* Still depends on acceptance of https://github.com/joemiller/bunchr/pull/1

* Veewee template for SLES => accepted

* Vagrant patch for Suse => accepted, but vagrant v.1.1.0 may take some time yet... I promise to remove that monkey-patch class the minute we can ;-) or we can wait...
