bitbake: toaster: fix unhandled exception

manage.py lsupdates throws DataError exception if the recipe can't be
saved to the MySQL database:
    django.db.utils.DataError: (1406, "Data too long for column 'license' at row 1"

Adding DataError exception to the list of exceptions should make
lsupdates to print a warning message and skip the recipe.
