distutils3: allow setup.py to be run from a different directory to ${S}

Sometimes setup.py can be buried deep in a source tree. This has
traditionally been solved with setting S to the subdirectory in
the source. However with the new pseudo changes, some python modules
make changes to files beneath ${S}, for example:

S = "${WORKDIR}/git/python/pythonmodule"

then in setup.py it works with source code in a relative fashion, such
as:

../../src

This causes pseudo to abort as it isn't tracking the paths. Therefore
implement the variable DISTUTILS_SETUP_PATH so that recipes can use:

S = "${WORKDIR}/git"
DISTUTILS_SETUP_PATH = "${S}/python/pythonmodule"

inherit distutils3

This allows the full source tree to be monitored, while distutils
can run setup.py from a location other than ${S}.
