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 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.
