Explicitly call the build command, as by doing this we get to pass -j.

In packages without any C extensions this is mostly a no-op as
bdist_wheel will call it anyway. However, this does make a big
difference to build time for packages with non-trivial C extensions:

  python3-cython:do_compile     204.8s -> 70.9s
  python3-lxml:do_compile       157.5s -> 92.4s
