Build fixes for Fedora

These fixes were necessary to build your packages on Fedora.

Build breaks:
- http://csc.mcs.sdsmt.edu/jenkins/job/ros-indigo-neo-relayboard_binaryrpm_heisenbug_x86_64/3/console
- http://csc.mcs.sdsmt.edu/jenkins/job/ros-indigo-neo-base-mp-500_binaryrpm_heisenbug_x86_64/6/console

The fix which was applied to `new_platformctrl_diff` should be applied to all of your packages. Their builds are succeeding, but the binaries that they are building are not being installed and are therefore not included in the package. You probably didn't notice because your're using `catkin_make` to build, which does not install. Use `catkin_make_isolated` and try to run your software to be sure it installing correctly before you release.

Thanks,
