Revert "nginx.conf: Use equal values for client_body_buffer_size and …

…client_max_body_size to avoid writing big files to disk"

Revert commit 4159eb5 due to nginx.conf already specifying a client_max_body_size that conflicts with the newly specified one.

In fact, client_max_body_size was set to `0`, disabling any limits, therefore preventing the registry from responding with 413 when a clint tried to upload large layers.

This needs further investigation to determine how Docker behaves with various registry settings.
