Fix win32pipe.WaitNamedPipe throw exception in windows container

[SLdragon]

WaitNamedPipe API call in the npipesocket.py module doesn't work correctly from inside a Windows container.
This is because currently WaitNamedPipeis not supported from inside of Windows Containers (however CreateNamedPipeClient works ok). It fails with ERROR_FILE_NOT_FOUND

what is missing for this to be merged?

[eNettMattD]

Any update on when this can be merged?

[StefanScherer]

I have tested this PR in a Windows container with a small test environment from StefanScherer/dockerfiles-windows#432 and it works.

Previously docker-compose just shows this error

ERROR: Couldn't connect to Docker daemon. You might need to start Docker for Windows. 

Thanks for the contribution. Ping @chris-crone @ndeloof WDYT? Is the recursion ok here for max 10 iterations?

[chris-crone]

LGTM, thanks @SLdragon and @StefanScherer !

Indeed, 10 iterations seems reasonable seeing what the code was before.

Thanks!
