Remove --universal options from homebrew rules.

 - they are ignored at the moment and therefore have not been used in a long time
 - on recent OS X these options are certainly wrong, so this is a prerequisite for merging

Add options/install_flags for boost/pcl.

 - as long as https://github.com/ros-infrastructure/rosdep/pull/304
   is not merged these will be ignored. If we merge this before rosdep
   is updated it will make testing that rosdep change slightly more easy.
 - install_flags will be used for `brew install`, but unlike options
   they are not checked for already installed packages
 - for boost --with-python see https://github.com/ros-infrastructure/rosdep/issues/330
