emulator opengles: improve TcpStream throughput

This patch improves the performance of the TcpStream implementation
on the host by disabling the Nagle algorithm, thus improving the
bandwidth of small packets.

When used with the corresponding change in the emulator, this
significantly improves the speed of OpenGLES emulation for many
applications.
