bitbake.conf: Set as default task umask of 022

Rather than trying to set the umask of every task to the correct
value for determinism, set one value globally. This uses a new
bitbake variable so bump the minimum version to match.

This fixes strange determinism issues in at least quilt-ptest,
valgrind-ptest and kernel-devsrc.
