extrahd: use udev rule to mount extrahd partitions

  the previous patches for
https://bugzilla.ipfire.org/show_bug.cgi?id=12863
introduce a new bug that slow devices are not mounted
at boot. So now udev calls the extrahd script with
the uuid.

Arne,

Can you double check the `udev 61-extrahd.rules` file?

I think it is missing the argument `mount`

RUN+="/var/ipfire/extrahd/bin/extrahd.pl mount udev-event"


Best regards,
Jon
