[Libssh] channel_read - Save read characters in "string"

[Aris Adamantiadis]

Ah yep. buffer_get is a void * because there is no reason you would read 
only character data. It works fine in C but c++ needs explicite casting.
command_output.assign((const char *) 
buffer_get(readbuf),buffer_get_len(readbuf));
