gnu: python-nautilus: Remove package.

This package dates from 2016 and looks inactive.  The packages that used this
as an input actually wanted nautilus-python (not currently packaged),
for (optional) integration with the nautilus file manager.

* gnu/packages/python-xyz.scm (python-nautilus): Remove variable.
* gnu/packages/gnome-xyz.scm (gnome-shell-extension-gsconnect)[inputs]: Remove
it.
* gnu/packages/sync.scm (nexcloud-client)[inputs]: Remove it.
* gnu/packages/syncthing.scm (syncthing-gtk)[inputs]: Remove it.
