cldr2qtimezone.py: report all missing zones, rather than just the first

When scanning the CLDR data, the script raised an exception if it
didn't recognize a zone ID.  Instead, collect up such unrecognized IDs
in a list and report them all at the end, so that whoever runs this
can do them all in one go, rather than doing one, running the script,
doing the next, running the script, ad nauseam.
