Integrating valgrind with sftp-server

[Kaushik Muthuravichandran]

Hi Damien,

I tried replacing the log file with $HOME in the Subsystem line below but
that still fails.

The alternate way that you suggested works fine.  With a limited amount of
testing that I did, the valgrind report looks clean.

Thanks for your help.

Regards,
Kaushik
