xserver-kdrive X11R7.1-1.1.0: Follow git renaming of xcalibrateext to xcalibrateproto.
* XCalibrate was migrated to X.org git, where most other packages live.
* After that, to follow new convention, its protocol definition part
(vs implementation library) was renamed to have "proto" suffix.
* That's state of git repo now, and if we patch older xserver release with
XCalibrate support, let's make sure that this is done in a manner compatible
with the git (as obviously, that will be base for new release).
* This means, xserver-kdrive cannot be any longer built with older XCalibrate
from previous CVS repo, and thus, it better be removed to alleviate confusion.
