[issue13424] Add examples for open’s new opener argument

[Éric Araujo]

New submission from Éric Araujo <merwok at netwok.org>:

The new opener argument to open and TextIOWrapper closed two bugs on this tracker: using O_CLOEXEC and replacing the unofficial 'c' mode (O_CREATE).  I think it’d be nice to have these as examples (maybe not in the docs of TextIOWrapper which are already huge, but for example in the os docs after the O_* constants).
