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

cpu: fix auxval parsing on big-endian systems
...
The words in auxval are encoded in native byte order.
I haven't added a test. This fix will be tested when s390x support
is added to the package.
