New amanda tcp default overwrites old udp configuration during upgrade

[Rob McColl]

The previous default configuration for the package written into /etc/inetd.conf was:
amanda dgram udp wait backup /usr/sbin/tcpd /usr/lib/amanda/amandad -auth=bsd amdump amindexd amidxtaped

This will be overwritten with the new default (the following) when upgrading from an existing installation of the package to the newest version:
amanda stream tcp nowait backup /usr/lib/amanda/amandad amandad -auth=bsdtcp amdump amindexd amidxtaped

This breaks existing installations and causes backups to fail.

Desired behavior:
If an old configuration is found when installing the package, ask the user what to do OR keep the existing configuration.

Same thing here, upgrade 10.04 -> 12.04. Backups were impossible until I restored the UDP line.
