ui: create /run/user/ dirs with proper permissions

"$XDG_RUNTIME_DIR defines the base directory relative to which user-specific
non-essential runtime files and other file objects (such as sockets,
named pipes, ...) should be stored. The directory MUST be owned by the
user, and he MUST be the only one having read and write access to it.
Its Unix access mode MUST be 0700."
