coreutils: fix reporting 'unknown' by `uname -p' and `uname -i'
This patch make `uname -p' and `uname -i' not reporting 'unknown'.
It refers a to Fedora's way to do this.
The coreutils upstream rejects to accept this patch, blaming the
'unknown' result to the kernel not providing enough information.
As on normal distros, `uname -p' and `uname -i' do not report 'unknown',
we refer to Fedora's patch to fix this problem.
