dropbear: increase default receive window size

Browse Source 
Increasing the receive window size improves throughout on higher-latency
links such as WAN connections. The current default of 24KB caps out at
around 500 KB/s.

Increasing the receive buffer to 256KB increases the throughput to at
least 11 MB/s.
