jailkit-2.3 ebuild patch fix for sunrise overlay

There’s an ebuild for jailkit version 2.3 on sunrise overlay. Unfortunately it has a bug that can cause severe headaches. It patches your /etc/shells in a VERY wrong way so that you can easily end up _only_ with /usr/sbin/jk_chrootsh inside /etc/shells. This can lock you out of your machine!

This behaviour is due to a patch that comes with the ebuild named: jailkit-2.3-destdir.patch.
In order to fix this behavior, I’ve patched the patch so that it works as it should. Now it just adds “/usr/sbin/jk_chrootsh” under all the previous shells you had in your /etc/shells file.
