[sysctl] Fix breakage on systems with older glibc

As predicted during code review, the sysctl(2) changes made systems with old glibc nearly unusable. About every command gives a: warning: process `ls' used the deprecated sysctl system call with 1.4 warning in the log. I see this on a SUSE 10.0 system with glibc 2.3.5. Don't warn for this common case.
