armbian-config-deb: add missing deps

armbian-config uses debconf-apt-progress which is part of debconf.

libtext-iconv-perl is needed to prevent the following error, when
uninstalling a package through debconf-apt-progress:

Can't locate object method "new" via package "Text::Iconv" (perhaps you forgot to load "Text::Iconv"?) at /usr/share/perl5/Debconf/Encoding.pm line 65, <GEN2> line 2.
dpkg: error processing package nfs-common (--configure):
