scripts/symbolize.py: ignore undefined symbols
With the introduction of dynamically linked TAs, symbolize.py may
encounter undefined (external) symbols when it parses the output of the nm
command looking for a symbol's address. The current code is not prepared
for that and will raise an exception. Fix the issue by ignoring lines that
have an unexpected format.
