This build fixes two tiny issues to minimize false positives in devicekit-disk's disk health status warnings.

The first one is this one:

http://git.0pointer.de/?p=libatasmart.git;a=commitdiff;h=66f3a5f5f6aac2b92b8b742899a3011b7cf380d2

This makes sure when judging the health of a disk we only take 'prefail' SMART attributes into account, not 'old-age'. Only the former are relevant for health, the latter only tell you that the device is not running under normal conditions, but that might be unrelated to the health.

The second one is this one:

http://git.0pointer.de/?p=libatasmart.git;a=commitdiff;h=6afdd8b2c56c09ab6d20d8d53aeee5a2faec44e9

Apparently some drives encode reallocated-event-count differently than others. This caused false positives. We don't need that attribute anyway, so we better don't check for this at all.

If this is not accepted into F11 people might be whining about Fedora complaining about their disks while they are not actually bad. Like this for example:

https://bugzilla.redhat.com/show_bug.cgi?id=495956#c3

Also, the two fixes are trivial, so not much could go wrong.

And of course I have tested this on a couple of SMART disk health blobs here. Seems to work.
