util.signal: Fix signalfd closure on non-Linux systems
The loop was incorrect for 0-indexed arrays. It started at signalfd_num, which
is the total number of signalfds, and decremented to 1 (condition was >0). So
if 1 signalfd was registered, it would check only signalfds[1]. At capacity
(32 signalfds) it would read past the end of the array. In every case, it
would always skip the entry at position [0], leading to a leak.
The swap-with-tail removal of the matched item used the post-decrement
operator, leading to accessing the array slot just beyond the tail.
Finally, it didn't break after finding a match. Probably harmless, but there
isn't expected to be more than a single entry per fd, as far as I can tell.
