Revert "cups: update package"

This reverts commit aa548af5a5e997b94df41b1da57232bd10b76612.
dvtm: update from 0.12 to 0.13
abduco: update from 0.1 to 0.2
mpv: Remove waf script from buildInputs.

Since b23dbb1a5dffbfa3abb47fcd0f1579ac2e6f29fc, if buildInputs contains
a plain file it is used as a setup hook. The waf script which is used
here in mpv however isn't a setup hook and also shouldn't be included in
buildInputs as it was kind of a no-op before already.
