virnetlibsshsession: Reflect API change in libssh

Browse Source 
As of libssh commit of libssh-0.11.0~70 [1] the
ssh_channel_get_exit_status() function is deprecated and a new
one is introduced instead: ssh_channel_get_exit_state().
It's not a drop-in replacement, but it's simple enough.
Adapt our libssh handling code to this change.
