bitbake.conf: move BB_NUMBER_THREADS and PARALLEL_MAKE to bitbake.conf

Currently, BB_NUMBER_THREADS and PARALLEL_MAKE default to unset and
are set in local.conf. Now that we have the automatic probing,
the default values can be set in bitbake.conf and an example of
explicitly defining how many tasks to run can be moved to
local.conf.sample.extended.
