docs: Fix empty parallelism argument

commit adc10f5b0a03606e30c704cff1f0283a696d0260 upstream.

When there was no parallelism (no top-level -j arg and a pre-1.7
sphinx-build), the argument passed would be empty ("") instead of just
being missing, which would (understandably) badly confuse sphinx-build.
Fix this by removing the quotes.
