* Fix Docker Failures on macOS from Failed Syscalls

On macOS, failed syscalls under Docker were not handled properly by
Python 2, which the Google Appengine development server runs under. Per
[PEP-0475](https://peps.python.org/pep-0475/), the correct response to a
failed syscall is to re-try the call, but this is not handled correctly
until Python 3. Therefore, in this commit we patch the Google Appengine
development server code to wrap the failing calls in try-except blocks.
This patching is performed each time the Docker containers start up.

For more details, see oppia#19271.
