scripts/decode_stacktrace.sh: better support to ARM32 module stack trace
Sometimes there are special characters around module names in stack
traces, such as ARM32 with BACKTRACE_VERBOSE in "(%pS)" format, such as:
[<806e4845>] (dump_stack_lvl) from [<7f806013>] (hello_init+0x13/0x1000
[test])
In this case, $module will be "[test])", the trace can be decoded by
stripping the right parenthesis first: (dump_stack_lvl) from hello_init
(/foo/test.c:10) test.
