[Review] Request from 'schubi2' @ 'yast/yast-inetd/review_140929_checking_nil'

Please review the following changes:
  * 7fec9ec packaging
  * a013b41 checking nil in GetServerBasename

NP: well, if you have now testsuite I think it is time to make method little bit more obvious what it do like:
```
def GetServerBasename(server, server_args)
  arg = server == TCPD_BINARY ? server_args : server
  return nil unless arg

  arg = arg.dup # do we really modify arg???
  
  server_path = result.strip.split(/[ \t]/).first
  return server_path if server_path.empty?

  File.basename(server_path)
end
```
