scripts/symbolize.py: remove spurious output '(out/arm/core/tee.elf)'

When a TA dump is processed, there is a list of ELF files just before the
call stack. However, when analyzing a TEE core dump, there is no such
list. Make sure this situation is properly handled to avoid displaying a
spurious message. This means fixing incorrect indentation in a
conditional.
