Subject: [PATCH] arping: Fix 1s delay on exit for unsolicited arpings

Commit 67e070d introduced 1s poll() delay for unsolicited arpings,
when using -U or -A, e.g.:

    # arping -A -c1 -I eth0 [IP address of eth0 interface]
    # arping -U -c1 -I eth0 [IP address of eth0 interface]

Restore correct condition.

Fixes: 67e070d ("arping: use signalfd() and timerfd() rather than signals")
Fixes: https://github.com/iputils/iputils/issues/536
Closes: https://github.com/iputils/iputils/pull/541
