collectd: move jshn.sh include to remove warning

Redmine-patch-id: 3680
If I build an image with the imagebuilder I get the following output
during image building:

../root-x86/etc/init.d/collectd: line 4: /usr/share/libubox/jshn.sh:
No such file or directory

To remove this messsage move include to the needed postion, so that the
message does not occur during image building on the host system anymore.
