sk-unix: add some missed error printing

In Virtuozzo tests we have seen uninformative errors:

(26.575039) 151187 fdinfo 6: pos: 0 flags: 2/0
(26.575076) sockets: Searching for socket 0x346d1 family 1
(666.230281 ----------------------------------------
(666.230586 Error (criu/cr-dump.c:1850): Dump files (pid: 151187) failed
with -1

So let's add some error messages to this stack.
