Remove log4net, newtonsoft deps from deb package

[HebaruSan]

Problem

Trying to install the .deb on Debian 12 fails with a message indicating log4net is missing:

root@MartinPC:/home/martin/Downloads# apt install ckan

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable

The following information may help to resolve the situation:

The following packages have unmet dependencies:
 ckan : Depends: liblog4net1.2-cil but it is not installable
E: Unable to correct problems, you have held broken packages.

Cause

The latest release of Debian seems to no longer include this package; "bookworm" doesn't show up in the package search listing:

https://packages.debian.org/search?searchon=names&keywords=liblog4net1.2-cil

However, our build process repacks log4net into ckan.exe, so we shouldn't need it to be installed in the OS:

Changes

Now log4net and newtonsoft are no longer listed as requirements for the .deb, because they are both repacked into the ckan.exe assembly. This should allow the .deb to be installed on Debian 12 and any other .deb-based OS that drops this package.

Fixes #3896.
