Fix key name to be the package name

I was not aware the rosdep key had to be the same as the package name. Otherwise I would get this error:

 catkin_package() the catkin package 'zivid_camera' has been
  find_package()-ed but is not listed as a build dependency in the
  package.xml

merged

mentioned in commit a11c79ef

Where does this error come from? Is it at the time of building the dependent package?

Yes, that is it.
