unbreak scp on NetBSD 4.x

e555d5cad5 effectively increased the default copy buffer size for SFTP
transfers. This caused NetBSD 4.x to hang during the "copy local file to
remote file in place" scp.sh regression test.

This puts back the original 32KB copy buffer size until we can properly
figure out why.

lots of debugging assistance from dtucker@
