kernel: split out lib-raid6

raid_pq.ko is needed by btrfs in 3.10+, so split it out into its own
package. Make it hidden as it does not provide any functionality on its
own.

kernel: btrfs supports raid6 in 3.10, thus depends on lib-raid6

btrfs now supports raid5/6 and added appropriate depenendcies for 3.10.
