scripts/decode_stacktrace.sh: silence stderr messages from addr2line/nm
[ Upstream commit 5bf0f3bc377e5f87bfd61ccc9c1efb3c6261f2c3 ]
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.
