[scponly] Patch for configure.in regarding hardcoded sftp-server path

[Thomas Wana]

Hi,

you can tell configure to not look for the sftp-server binary
if you supply a hardcoded path on the command line, e.g.
./configure --with-sftp-server=/usr/lib/sftp-server

However, if you also supply --enable-scp-compat, configure still
tries to find the sftp-server binary, and then fails. The
following patch fixes the problem.
