multilock: Fixed a bug in the sleep command

The timeend - time(NULL) happened to be negative and that called
the pselect syscall with a negative number and the tool finished
with an error.

The case that ran was `simple_block`, when it got to the 2 second
sleep command it did it in two iterations and in the second
iteration the tv_secs was calculated to be minus 1 resulting in
an error from the pselect call.
Output:
Line   34: sleep 2
Waiting for clients
About to sleep for 2 secs
Waiting for clients
About to sleep for -1 secs <- Error
...
err: select failed with ERRNO 22 "Invalid argument"
Receive failed ERRNO 22 "Invalid argument"
Unexpected response
1 errors
FAIL
