set uwsgi buffer size from 4096 to 32768

[pazepaze]

• ckan closes connection when request header size exceeds 4069 bytes
• this can easily happen when requests include long cookies (e.g. oauth tokens) etc.
• max setting for buffer size would be 65535 bytes, see https://uwsgi-docs.readthedocs.io/en/latest/ThingsToKnow.html

fixes #50

Thanks @pazepaze this looks very sensible. Would you mind submitting a PR on the main CKAN repo example uWSGI config file?

Thanks!
