escaping ROS_PACKAGE_NAME fails when set cmake version at rosconfig

[dpinol]

Related to ros/roscomm#245 :

Please try this:

1. Create a "/opt/ros/hydro/share/ros/rosconfig.cmake" file with only this contents

cmake_minimum_required(VERSION 2.8.3)

2. Create a dry package which uses a rosconsole macro and compile it (eg. https://github.com/dpinol/ros_tests/tree/master/cmake_policy) with "make VERBOSE=1". You'll see that it has the wrong scaping for the package name: -DROS_PACKAGE_NAME="'"cmake_policy"'"
   Compilation will fail.
