scripts/decode_stacktrace.sh: wrap nm with UTIL_PREFIX and UTIL_SUFFIX

Patch series "scripts/decode_stacktrace.sh: better support to ARM32".


This patch (of 2):

Since System.map is generated by cross-compile nm tool, we should use it here
too. Otherwise host nm may not recognize ARM Thumb-2 instruction address well.
