[aarch64] spotify-player build fix

This fixes the build of spotify-player on aarch64 by pulling in the
last C version of cpu_aarch64_openbsd before BoringSSL switched to C++
which provides the missing OPENSSL_cpuid_setup() symbol.

This is needed since the #ifdef maze ends up defining NEED_CPUID for
OpenBSD/aarch64, but for some reason this file was lost in aws-lc.

There are many things not to like about this, but it might be preferable
to disabling assembly altogether on aarch64 (which I haven't really
looked into).

A runtime test by a spotify user would be nice.

The same sort of gymnastics should work for ncspot as well. I haven't
tried.
