MINOR: [Python] try harder to set up s3_server fixture

[h-vetinari]

In conda-forge, when running the aarch tests in emulation, we regularly run into the issue that the fixture setup fails. Extending the timeouts fixes this. Since it only happens once per session, it doesn't hurt to take a little bit more time.
