It's not currently possible to set the build tree to be somewhere we
control, but we know it will always be in the build directory alongside
the setup.py so we can [cleandirs] that.

MJ: helps with build/lib directory being added when a recipe is rebuilt
in the same WORKDIR multiple times, e.g.:

Just rebuilding python3-tqdm in the same TMPDIR after cherry-picking this:

$ buildhistory-diff -p buildhistory build-minus-1 | grep PKGSIZE
python3-google-auth/python3-google-auth: PKGSIZE changed from 11752510 to 1315694 (-89%)
python3-googleapis-common-protos/python3-googleapis-common-protos: PKGSIZE changed from 7108856 to 794024 (-89%)

$ wc -l python3-google-auth/2.29.0*/image/usr/lib/python3.12/site-packages/google_auth-2.29.0.dist-info/RECORD
