user.localbase is a real sysctl, but with a default value returned
when sysctl(3) is used.

The getlocalbase() function should not depend on this default value,
since it contains an identicl default value that can be returned if
sysctlbyname fails (or rather returns a zero length string in case
no other value has been written to the kernel).
