Tobias Klauser 92a0ff1e1e cpu: don't panic on error reading /proc/self/auxv ...

On Android /proc/self/auxv is not readable, leading to a panic in init.
Instead of panic'ing in this case, introduce the Initialized global bool
to report whether the CPU features were initialized i.e. /proc/self/auxv
was successfullly read.

Fixes golang/go#30413
