Bug#884128: libical: don't release with buster

[Emilio Pozuelo Monfort <pochu@debian.org>]

Source: libical
Version: 2.0.0-1
Severity: serious

Hi,

We have src:libical3 now, so libical2 should be dropped before the
freeze. We shouldn't need to release buster with both libical 2 and 3.
Filing this bug so we don't forget about that.

Emilio
