community/zabbix: fix setup subpackage
The setup package should contain the database schema's, but only
contained Makefiles. The reason is that database
directory was copied
from $builddir
, but the source is copied for each database, where the
actual build is done.
So copy the database schema's from $builddir-postgresql
, like is done
for other subpackages, and make sure the Makefiles
don't end up in the
package.
