Hi,

Ever since the package version in buster, debsecan gets installed
automatically when you let "recommends" install.
It also means that it gets installed automatically during a dist-upgrade to
buster.

This means that root starts receiving emails daily from that tool even though
one is not using debsecan or expecting to use check_debsecan.

I would argue that because of those automatic emails getting sent out by
default, debsecan should be moved out to the "suggests" section of this
package.
