opkg-utils: clear update-alternatives database on uninstall

Browse Source 
When uninstalling update-alternatives, it doesn't seem to
make much sense to keep the update-alternatives database
around.
In particular when removing packaging data, e.g. due to
read-only rootfs, update-alternatives is removed from
the target file system. Leaving its database around
serves no purpose in that case as there is no way to
use it afterwards anyway.

This frees close to 700KB of (uncompressed) space in
a busybox based environment.
