commit 0bea92bd73c680b47482218c09f7987069d23ad8

dbus-proxy: Make it work if XDG_RUNTIME_DIR not set
The socket directory then ended up in $HOME which was read-only, so
we couldn't create the socket. We solve this by putting the sockets
in a subdirectory and always making this directory writable in the
proxy.
