tools/trap: Fix issues in symbol while printing call stack details

- This patch fixes the issue of missing letters of symbol name
while printing the assert log.
- Earlier, we were not printing symbol when addr2line was not avaliable
but now, we print symbol name irrespective of addr2line output.
- As c++ symbol length are very big, so, we print it in specific
format [first 20 chars ... last 20 chars].

Before:
Stack_address	 Symbol_address	 Symbol_location  Symbol_name		File_name
 User stack
Symbol not found for address: 0xe16f049
Symbol not found for address: 0xe17f490
Symbol not found for address: 0xe16e9a9

Symbol not found for address: 0xe16eb37
