fix: include customizations folders into velocity path

[Yuriy Movchan]

In older version like 4.3.x we applied next block from path:

-        <property name="resourceLoaderPath" value="#{'%{idp.views:%{idp.home}/views}'.trim()},%{idp.home}/system/views" />
+        <property name="resourceLoaderPath" value="/opt/gluu/jetty/idp/custom/pages,#{'%{idp.views:%{idp.home}/views}'.trim()},%{idp.home}/system/views" />

In latest build we not apply same changed to IDP configuration in idp-conf module

We need to apply this patch and check if it works well with actual IDP version

FYI: When I tried to apply this fix it in CE 4.5, it didn't solve the issue. I can help with testing when the fix is ready too.
