package/libinput: remove python tools scripts

Some libinput tools are actually python scripts and requires at least
tree python modules: libevdev, pyudev and pyyaml:

libinput]$ file *

libinput-replay:                    Python script, UTF-8 Unicode text executable

Since for now we do not have a python-libevdev package, this commit
unconditionally removes Python scripts.
