Rebuild against current db.
Remove unneeded zlib dependency.

This reverts commit c9c33d0f.

Downgrading the db support requires users to recreate their databases.
As pointed out in
#3
we likely want to just completely remove the db support instead.

Fixes #2

Add license files also to split packages.

Following /usr/share/doc/postfix/DB_README we are extending the `CCARGS`
and `AUXLIBS` environment variables to build and link against db5.3
instead of db.

Fixes #1

This reverts commit 97d9cd64.

The included patch has no effect on the linking strategy of the build.
The build system of postfix is unfortunately overly complicated for no
reason and other link flags need to be handed in over `AUXLIBS` and
header include locations via `CCARGS`.

Fixes #1.
