python_setuptools_build_meta: clean the build directory in configure

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 pyproject.toml so we can [cleandirs] that.

MJ: this was later reverted in a532cb50151d773c1c351ffccf4d47a37f26f8aa:
  This is not needed: setuptools.build_meta does the build under a new
  temporary directory.

but the builds in scarthgap aren't using new temporary directory yet,
so this is still useful there:

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

$ buildhistory-diff -p buildhistory build-minus-1 | grep PKGSIZE
python3-tqdm/python3-tqdm: PKGSIZE changed from 3309408 to 426880 (-87%)

$ wc -l python3-tqdm/4.66.3*/image/usr/lib/python3.12/site-packages/tqdm-4.66.3.dist-info/RECORD
  297 python3-tqdm/4.66.3-old/image/usr/lib/python3.12/site-packages/tqdm-4.66.3.dist-info/RECORD
   41 python3-tqdm/4.66.3/image/usr/lib/python3.12/site-packages/tqdm-4.66.3.dist-info/RECORD
