remove build artifact directory in build.sh

[mattip]

When running the aarch64/ppc64le builds, it is important there be only one _sysconfigdata__* file in the build directory, since these are run 4 times (pypy3.8, pypy3.9) * (openssl1.1, openssl3.4)

So make sure this fix goes into the next PR:

whoops. Spent way too long reaching the conclusion that I didn't do this for v7.3.11 ☹️

Also: export the variables instead of setting them:

Perhaps a better reminder is an open PR with the required changes (or even merging those)?
