	Closes-bug: 1274470

* Fix accessing nested-dir scripts from nested-dir agent templates.
	This works the following way: if path to agent template is,
	.g. <someHash>/template/agent/SqlServerCluster/FailoverCluster.template,
	nd it references script file '/ImportCoreFunctions.ps1', then it will
	e searched in '<someHash>/template/agent/scripts/' dir, but if it
	eferences 'Failover-Cluster.ps1', it will be searched in
	<someHash>/template/agent/scripts/SqlServerCluster/' dir.

	o the root-like agent dir '<someHash>/template/agent' corresponds to
	oot-like scripts dir '<someHash>/template/agent/scripts', and the
	ctual script file will be searched immediately in root-like scripts
	dir if it starts with '/' (absolute name), or there will be
	'rest-dirs' between root-like scripts dir and the script filename if
	the script filename is a relative one. 'rest-dirs' is the difference
	between root-like agent dir and the actual parent dir of the agent
	template which references the script dir. As you see, the
	abovementioned example is much clearer than the explanation.
	Closes-bug: #1271578
