Adding support of InitD scripts.

Created a set of init.d scripts to be able to start as a service the
following:

* Mesos Local
* Mesos Master
* Mesos Slave

We also added a profile shell to bootstrap the environment of those
init.d scripts.

Source
src/deploy/mesos-profile-env.sh.in

Installed at
_prefix_/sbin/mesos-profile-env.sh
Export the location of _prefix_/lib/libmesos.so as MESOS_LIB

The `mesos-profile-env.sh` now exports the location of `libmesos.so`.
This could be usefull when integration with other libraries such as
_Spark_.
