Preserve AirflowTaskTimeout when timeout logging fails
---
### Why
`handle_timeout()` logs a timeout message before raising
`AirflowTaskTimeout`. The task runtime sends those logs through a pipe handled
by the supervisor. If that pipe has been closed (for example, because the
supervisor has exited), the logging call can raise `BrokenPipeError` instead.
This masks the original timeout, causing the task to fail with a logging
error rather than `AirflowTaskTimeout`. This exact sequence appears in the
production traceback in #64212.
### What
Suppress `OSError` raised while logging from `handle_timeout()` so a failed
log write cannot mask the timeout. `handle_timeout()` will still raise
`AirflowTaskTimeout` after a logging failure. Non-OSError exceptions from the
logging stack are deliberately left out of scope.
