[PATCH 7/8] tools/build-docs-container: allow passing extra args to $OCI run

[Antonin Godard <antonin.godard@bootlin.com>]

Add a OCI_RUN_EXTRA_ARGS env variable to allow customizing the arguments
passed to the podman/docker run command. For example:

  export OCI_RUN_EXTRA_ARGS="--env=SPHINXOPTS=-W --keep-going -j1"

To limit the number of threads used by Sphinx. This is especially useful
for parallel builds.
