Revert "owsd: hotplug: map aliases against interface on ifup"

This reverts commit 051826305e.

Reason for revert: This appears unnecessary as individual ifup events
are already being generated for main and alias interfaces. The logic
is also broken. It causes owsd to be reloaded every time there is ifup
event on alias interface, regardless of owsd configuration.
