Create an RPM for the external CLI

This adds an option to creat an RPM for the external CLI. It uses the rpmbuild
to create the rpm.

The cli dependencies in the lua libraries and files was changed to be relevant
to the current directory.

It would copy all the lua depnedencies with it, including the lua so files.  To
run either call from inside the cli:
make rpm

or from the rpmbuild directory call
make

To install the cli use yum for example
sudo yum install ./RPMS/x86_64/osv-cli-1.0-1.fc20.x86_64.rpm

To uninstall do:
sudo yum remove osv-cli

After installation, you can call
cli
