package/kodi-pvr-addons: Prepare to split into addon-specific packages

The PVR addons formerly being part of the xbmc-pvr-addons package were
split into seperate packages being hosted on https://github.com/kodi-pvr

This patch removes the old PVR addon package to prepare for the new
PVR addon packages being added as subsequent patches.

[Thomas: keep alphabetic ordering for addons, as noticed by Yann
E. Morin.]
