rename manifest.xml before running rosdep

rosdep confuses manifest.xml and package.xml.
this is a solution to solve that problem by renaming manifest.xml.

* add a script `rosdep-update.sh` and use that script in `jsk.rosbuild`
  * rename manifest.xml before running rosdep
  * rename those files to manifest.xml again after running rosdep
  * run rosdep with -i option to ignore packages which included in source code
