torture: Make kvm-remote print diagnostics on initial ssh failure

Browse source

Currently, if the initial ssh fails, kvm-remote.sh gives up, printing a
message saying so.  But it would be nice to get a better idea as to why
ssh failed.  This commit therefore dumps out ssh's exit code, stdout,
and stderr upon ssh failure for diagnostic purposes.
