env-hooks: install env-hook to etc/orocos/OROCOS_TARGET/profile.d

The env-hook sets the OROCOS_TARGET environment variable if not set and adds the lib/orocos directory
of the install-space and all entries of the CMAKE_PREFIX_PATH (for catkin workspaces) to the
RTT_COMPONENT_PATH.

The scripts in etc/orocos/OROCOS_TARGET/profile.de will be sourced in lexical order by a new setup.sh
script located in the orocos_toolchain repository.
