Bug#905697: kdepimlibs: don't depend on libical

[Emilio Pozuelo Monfort]

Source: kdepimlibs
Version: 4:4.14.10-10
Severity: serious
Control: block 884128 with -1

Hi,

libical2 from src:libical is superseded by libical3 (src:libical3).

Please either port kdepimlibs to libical3 or try to disable the
libical support, so that we can only ship src:libical3 in buster.

Thanks,
Emilio
