[PATCH v3 2/2] scripts/decode_stacktrace.sh: better support to ARM32 module stack trace

[Xiong Nandi]

Sometimes there is special characters around module name in stack trace,
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 firstly:
(dump_stack_lvl) from hello_init (/foo/test.c:10) test
