This reverts commit 75c9936737a6ba991d4ef187ddc9d51bc0ad0998, reversing
changes made to 7f13f5cd5f5a518638b15d7225eae2d88ec1efb5.

I don't think `runZigBuild` belongs in std.testing. We already have
`test/standalone/*` for this.

Additionally test names should explain what they are testing rather than
referencing GitHub issue numbers.
