Subject: scripts/decode_stacktrace.sh: silence stderr messages from addr2line/nm
Sometimes if you're using tools that have linked things improperly or have
new features/sections that older tools don't expect you'll see warnings
printed to stderr. We don't really care about these warnings, so let's
just silence these messages to cleanup output of this script.
