ssh: Add support for libssh2 read timeout

Hook the new (1.11.0 or newer) libssh2 support for setting a read timeout
into the SERVER_RESPONSE_TIMEOUT option.  With this done, clients can use
the standard curl response timeout setting to also control the time that
libssh2 will wait for packets from a slow server.  This is necessary to
enable use of very slow SFTP servers.
