Define audit-event open parameters consistently

as in
Doc/library/io.rst:   .. audit-event:: open path,mode,flags io.open
Doc/library/os.rst:   .. audit-event:: open path,mode,flags os.open
to avoid triggering a race-condition in Sphinx
that causes non-deterministic output.

See https://reproducible-builds.org/ for why this matters.

Fixes: #121874

This patch was done while working on reproducible builds for openSUSE, sponsored by the NLnet NGI0 fund.
