Elliott Hughes 02df7388f1 sysconf(): implement cache queries. 
This is a bit disappointing. I'd not implemented this in the past
because it wasn't available on all platforms, and -- although the
riscv64 implementation was just a cool optimization -- I thought that
the /sys stuff was actually portable, until I ran it on arm64 hardware.
So here we have getauxval() for riscv64, /sys for x86-64, and our best
guess based on ctr_el0 for arm64.

Bug: http://b/294034962
Test: ran tests on the host, an arm64 device, and riscv64 host and qemu
