Recognise Linux Swap Suspend and Software RAID partitions (#709640)

Recognise in kernel, Linux Swap Suspend partitions.  (When hibernated
the kernel write the RAM out to swap space and changes the magic string
from swap space to suspend).  Recognition required either
libparted >= 1.8.8.1 or blkid from util-linux >= 2.15 or before that
blkid from e2fsprogs >= 1.39.

Recognise Linux Software RAID partitions.  Recognition requires blkid
from util-linux >= 2.15.

Example:

    # blkid /dev/sda10 /dev/sda11
    /dev/sda10: ... TYPE="swsuspend"
    /dev/sda11: ... TYPE="linux_raid_member"

    # parted /dev/sda print
    Model: ATA SAMSUNG HM500JI (scsi)
    Disk /dev/sda: 500GB
    Sector size (logical/physical): 512B/512B
    Partition Table: msdos

    Number  Start   End     Size    Type      File system     Flags
    ...
    10      361GB   362GB   1074MB  logical   swsusp
    11      362GB   363GB   1074MB  logical                   raid
