Reordered Makefile targets, declared PHONY
Makefile: Use use only one dash in version for RPM
Updated RPM build dependencies
Fix manpage and initscript install for RPM
Initscript logging fallback for non-LSB systems

* Removed sourcing of unused /lib/init/vars.sh
* Instead of using log_* LSB functions unconditionally, fallback to RHEL
  /etc/init.d/functions or plain echo messages if needed. Typically, this
  suppresses the need to install redhat-lsb on RHEL systems, saving 290MB+
  in pulled dependencies.

Thanks to ExecDevOps on GitHub for the report and suggestion.
