Give extraction stderr more context, and suppress normal cpio stderr junk.
cpio will write a useless "N blocks" message to stderr without --quiet, so
use that.
When we show extraction's stderr to the user, first write a line explaining
what it is, and also don't forget to strip the trailing newline, since
.warning() writes its own.
