doc/Makefile: Fix build dir setting

The commit 4d8da8ed ("Docs: Update sphinx targets with the build directory")
introduces an additional variable intending to allow an user to specify
a different build directory. Since the variable is not writable from the
outside and also the Docker container used to build doc.coreboot.org
calls the Makefile with `BUILDDIR` instead of `SPHINXDIR`, building the
documentation within the container doesn't work anymore.

Thus, change the variable name to `BUILDDIR` and make it writable.

Steps to reproduce:

  cd util/docker
  make doc.coreboot.org
  make docker-build-docs
