patches/openwrt: drop patch to fix removing dirs

This patch doesn't seem to work as it should and randomly includes
directories in the file list which makes some installations print a
warning:

    %: opkg install xinetd
    //usr/lib/opkg/info/xinetd.postinst: line 261: /etc/init.d/: Permission denied

-+deletion in the event that a package leaves an empty directory during package
-+removal.
