[PATCH 6/8] tools/build-docs-container: allow running non-interactively

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

When running this script from another one, it can be useful to run the
OCI run command non-interactively, especially when running concurrent
builds. Add a RUN_NON_INTERACIVE env variable that can be set to 1 to
remove the --interactive and --tty options from the run command.
