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.
