No longer run the ifblacklist_migrate.sh script upon installation.

This script was used to comment out DHCP type network interface configurations
in /etc/network/interfaces as otherwise NM would mark such devices as
unmanaged. This script was buggy though and sometimes created a broken network
configuration.
Since debian-installer in wheezy (7.0) will create proper configuration for NM
if the network-manager package is part of the installation, this is no longer
necessary.
If users make a minimal system installation and install the network-manager
package afterwards, show a warning in postinst if we find any interface
configurations in /etc/network/interfaces.
(Closes: #688355, #690987, #606268)
