env-hooks: install env-hook for ocl-lua to etc/orocos/OROCOS_TARGET/p…

…rofile.d

The env-hook adds the installation folders of the ocl-lua modules to the LUA_PATH/LUA_CPATH environment
variable.

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.
