bitbake: toasterui: log OSErrorException metadata events

OSErrors occurring in toaster.bbclass are converted to
OSErrorException metadata events. They were then being swallowed
as unprocessed events by toasterui, which made them difficult
to spot.

Explicitly catch OSErrorException events and log them so they
are easier to spot and debug.
