[gentoo-dev] Update for bzr.eclass

Hi all,
Find below a small update for bzr.eclass.

Sometimes it is convenient to unpack the sources in a location
different from ${WORKDIR}/${P}. The patch makes this configurable via
a new EBZR_UNPACK_DIR variable. The default location doesn't change,
so there should be no issues with backwards compatibility.

Please review.

Ulrich
