hostname issue on Solaris

[tropikhajma]

The hostname(1) command on Solaris does not support the '-s' and -f' flags. See https://docs.oracle.com/cd/E88353_01/html/E37839/hostname-1.html
As a result, the rabbitmq build produces several usage errors when the hostname command execution is attempted, but I am not sure if there's any impact.

Still, the attached patch fixes the issue for me on Solaris 11.4

I will convert this issue to a GitHub discussion. Currently GitHub will automatically close and lock the issue even though your question will be transferred and responded to elsewhere. This is to let you know that we do not intend to ignore this but this is how the current GitHub conversion mechanism makes it seem for the users :(

The .mk changes seem fine and won't affect anyone but our development team and contributors. They are only used when nodes are built and started from source.

As for the .ocf file change, it is maintained by the OpenStack community. It seems reasonably safe to me.

Please submit a PR.
