image-rotate: adding missing nodelet dependency

Executing 'bitbake packagegroup-ros-world' showed the warning:
WARNING: QA Issue: image-rotate rdepends on nodelet but its not a build dependency? [build-deps]

On a clean build, 'bitbake image-rotate' failed with:
|   Could not find a package configuration file provided by "nodelet" with any
|   of the following names:
|
|     nodeletConfig.cmake
|     nodelet-config.cmake
|

Hence, this commit adds the missing dependency on nodelet.
