debian/patches: Remove patch that adds px.

This caused way too many messages filling up my ~/.xsession-errors with:

    Gtk-WARNING **: Theme parsing error: nautilus.css:128:20: 'px' is not a valid color name

Since I plan on sticking with GTK3.4 for the moment, that's going to be dropped.
Remove Zukitwo.emerald.

I don't know what it is for and it can be retrieved quickly from the repo
history.
Update.
