bitbake: bitbake-worker/runqueue: Add support for BB_DEFAULT_UMASK

Currently each task has to have a umask specified individually. This
is leading to determinism issues since it is easy to miss specifying
this for an extra task.

Add support for specifing the default task umask globally which
simplifies the problem.
