tunnel_to: shrink huge buffer size

Browse Source 
the buffer buff was only used for the initial handshake packets,
which in all supported protocols are usual less than a 100 bytes,
with user/pass and dns name at maximum we'd require 768 bytes,
which still leaves us a formidable 256 bytes for the rest of
the packet.
this fixes a segfault with microsocks which on musl uses tiny
thread stack sizes of 8KB.
