sysctl binary: Reorder the tests to process wild card entries first.
A malicious user could have passed in a ctl_name of 0 and triggered the well know ctl_name to procname mapping code, instead of the wild card matching code. This is a slight problem as wild card entries don't have procnames, and because in some alternate universe a network device might have ifindex 0. So test for and handle wild card entries first.
