reproducible-builds.rst: show how to build a single package

Browse Source 
Add a bit to the "Can we prove the project is reproducible?" section to
show how OEQA_REPRODUCIBLE_TEST_TARGET can be used to test a single
package (rather than the world build), as this may be useful for
maintainers.

This defaults to including a ``world`` build so, if other layers are added, it
would also run the tests for recipes in the additional layers. Different build
targets can be defined using the :term:`OEQA_REPRODUCIBLE_TEST_TARGET` variable
in ``local.conf``. For example, running reproducibility tests for only the
``python3-numpy`` recipe can be done by setting::
OEQA_REPRODUCIBLE_TEST_TARGET = "python3-numpy"
in local.conf before running the ``oe-selftest`` command shown above.
Reproducibility builds the target list twice. The first build will be run using
:ref:`Shared State <overview-manual/concepts:Shared State>` if available, the
second build explicitly disables :ref:`Shared State
<overview-manual/concepts:Shared State>` except for recipes defined in the
:term:`OEQA_REPRODUCIBLE_TEST_SSTATE_TARGETS` variable, and builds on the
specific host the build is running on. This means we can test reproducibility
builds between different host distributions over time on the Autobuilder.
