Netfilter sysctl defaults were moved into specific kmod-packages from
base-files. When we wanted it to configure in base-files, those values
are overwritten by file sysctl-nf-conntrack.conf provided in the package
kmod-nf-conntrack. We don't need to set it twice and remove it from
base-files and change it only in kmod-nf-conntrack.

In Turris OS 3.x opkg was the package containing
/etc/opkg/distfeeds.conf. This file with TOS 4.0+ was moved by upstream
to base-files. This means hat we also have to move postinst for that
file update to base-files from opkg package. This should fix OPKG feeds
being reseted by update.

Foris does not know from which country Prague is so it uses additional
option to specify that it is from Czech Republic. In default it was not
provided so Foris was not showing default setting correctly. This should
fix that and Prague is now set as default location.
