This reverts commit d83af48f.

It doesn't fix the issue and we have a correct solution now.

This patch was pinpointed to possible cause problem of SFP module to not
be brought up at all.

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.

Omnia macs are set by u-boot so we do not need update_mac script and
new version of that script does not work correctly on Omnia as it has
lan0-4 and not lan1-5 as on Turris 1.x.

The implementation was invalid because it scanned only first line in
whole range. This new one scans every line in range for version field so
it correctly locates version.

updater-supervisor handles non-existence of this option and its
non-existence is a feature we want so Foris is able to detect difference
between disabled and not set autorun.

Upstream maintainer does not want to accept default root login. No clear
reasons given. This makes from this patch hack not something we are able
to push to upstream.

Upstream prefers to use pip to install dependencies to build_dir instead
of global host directory. That means that these patches are not going to
be upstreamed and we replaced them with upstream suggester approach.

I hope that this is last fix.

Previous commit reverted wrong patch so this is the fix of that.
