allow --monitor to be run by non-privileged use. 

Providing --no-sharing is given, monitoring should be permitted.

Unfortunately the kernel current rejects GET_DISK_INFO and
GET_ARRAY_INFO for non-privileged users which is unjustified.
The info is available in sysfs and we could get it from there,
but for now, require the kernel to be fixed.
