Fix #263: Incorrect device name from iostat

Using sysstat.ioconf configure file to determine the device name based
on its major and minor numbers gives a wrong name for xvd* devices with
big minor numbers.
Don't use it any more as there are other ways to find the name (e.g. we
can read the symlink in /sys/dev/block/).
