Pets considered any noise made by hero as whistling

In 3.6.2 parts of the wakeup code were merged together, and this
caused pets consider any noise made by the hero - such as hitting
iron bars or digging - as whistling for them to come to the hero.

Change it to only consider actual whistling and ringing a bell.
