scripts/symbolize.py: update help text
Commit 546291f4de9b ("trace: make output more compact") has changed the
format of the abort and panic dumps. Update 'symbolize.py --help'
accordingly.
The help text is also reworked slightly to make it clear that the
script may be used with all kinds of crash dumps (TEE core or TA,
aborts and panics).
