Configuration override options was misleading. In reality those are
options you most probably don't want to mess too much with so let's call
them rather advanced options.

This also moves PUBLISH_BRANCH in example configuration file to
section: don't mess with. This is because now we provide it from
defaults and user just should not mess with it unless he know what he is
doing.

Parameter -e is now obsolete and by default, we want to build everything.
Removed it from turris-build.conf.example

Because of that we or users don't need to select packages in make
menuconfig which we or they want to build. Now each package will be selected
but not compiled which depends on user choice.

Also, compile_pkgs shouldn't be run under root or with sudo. Do it as
normal user.

Commiting basic building script. Some functionality is already there, what is
missing is handling branches and freezing stuff, correct version setup (no need
in development for now), userlist generation and medkit creation (no need till
we build at least a big part of packages).
