Checkmk Werk 14602: cmk-update-agent: Use configured var directory

ID: 14602 Title: cmk-update-agent: Use configured var directory Component: agents Level: 1 Class: Bug fix Version: 2.2.0i1 The agent updater used to use the fixed directory <tt>var/lib/check_mk_agent/</tt> to unpack its CA certificates regardless of what was configured in the rule "Installation paths for agent files" Technically spoken, this means that the agent updater now respects the <tt>MK_VARDIR</tt> environment variable.
