Fix Debian bug #534604: Checking md10 and above

| check_linux_raid malfunctions if system has software RAID devices with
| two or more digits.  For example, for system having /dev/md10,
| /dev/md11 etc, the plugin returns 'UNKNOWN' in automatic mode (if RAID
| devices are manually specified it works).  Also, if system has both
| one-digit, and two-digit RAID devices, the two-digit devices are
| silently ignored in checks, which is even more problematic.
