disable Nagle's algorithm by default

Nagle's algorithm is harmful with the write-write-read sequence
during keepalive, so we disable it performance for users using
keepalive.  We always write headers with a separate write
because Rack response bodies may not always be ready for writing
when headers are.

This requires Unicorn 3.3.0
