HYD-5353 Manager install update to handle EL7 commands

As with other areas of code, the spec file which handles installation
of the manager source and byte code-files and associated tasks,
requires updating to handle system commands specific to EL version.
The canonical example of this is the issuing of firewall control commands.

  - update spec file for chroma-manager to handle firewall control on EL7
