Defer to getpagesize() in sysconf().
It makes sense that callers to getauxval() should have to pay for a
search --- that's exactly what they're asking for. But it seems silly
and unfair for the same to be true of sysconf() --- that's just an
implementation detail. Call getpagesize() directly instead.
