Subject: [PATCH v2] scripts/decode_stacktrace: Look for modules with .ko.debug extension

In Chromium OS kernel builds, we split the debug information as
.ko.debug files, and that's what decode_stacktrace.sh needs to use.

Relax objfile matching rule to allow any .ko* file to be matched.

Changes since v1:
 - Added quotes around name pattern.

(note that the line in 81 chars now, but there is a precedent below, that
does not split a much longer line in $(), so hopefully this is ok)

akpm: To replace the existing patch in mmotm, thanks!
