Drop redundant files
Things have moved around between repositories and these files are now unnecessary.
-
/etc/xdg/plasmashellrc
used to set the shell to launch but that is already handled by the launch scripts of Plasma Bigscreen itself -
/usr/bin/cec-daemon.py
was used to provide CEC input but that has been replaced by the dedicated plasma-remotecontrollers program -
/etc/udev/rules.d/40-uinput.rules
made it possible to use the kernel's uinput module as a regular user, but this file is now provided by plasma-remotecontrollers (since that's the program that needs that access in the first place)
