Hello,

There is the Xfce 4.10 PPA by the Xubuntu Team :
https://launchpad.net/~xubuntu-dev/+archive/xfce-4.10

But it doesn't have xfce4-session 4.10.2 (only 4.10.1).
The latest release seems to be the 4.10.1 version, at least for now :
http://git.xfce.org/xfce/xfce4-session/

So I think you have two options :
1.Install the Xfce 4.10 PPA and wait for an update.
2.The patch seems to be easily applicable, even on Xfce 4.8 :

To make a .DEB package (instead of using "make install"), you can use 
checkinstall (which is available on the ubuntu repos).
Then, you can install it with dpkg -i <package>.
