bitbake: toaster/widgets.py: avoid divide by zero issues

There can be cases where the variables being used
to divide in build percentage expressions can be
zero. For example, a setup consisting of only local
repos will have repos_to_clone=0 and will generate
a divide by zero scenario.
Fix this by checking the divisor in such cases.
