Inject taskpid into log records via our log handler

It turns out that while log filters added with addFilter are only associated
with that logger, and not its children, handlers are inherited, and handlers
can be filters.   So, let's add filtering to our existing LogHandler class
which dispatches our log records as bitbake events.
