Bug 25068: Fix koha-common.install directives

Bug 24735 removed etc/searchengine/queryparser.yml, which removed
the need for koha-common.install to install the following file:
debian/tmp/etc/koha/searchengine

This patch removes that line and causes the Koha packages to build
correctly again.

To test:
0) Apply patch
1) Build a Koha package using one of the following methods:
- https://wiki.koha-community.org/wiki/Building_Debian_Packages_-_The_Easy_Way
- https://hub.docker.com/r/koha/koha-dpkg
- https://gitlab.com/minusdavid/koha-deb-builder-docker
