scripts/symbolize.py: print path of ELF files

Show which file corresponds to each ELF binary in a TA. Symbolic links
are followed, so that dynamic libraries are likely shown with their
user-friendly name (libfoo.so) rather than their UUID (<uuid>.elf) --
see commit 01b8b5c ("TA dev kit: when building a shared library,
create symlink with UUID").
