I think this is the wrong version of libguestfs-winsupport.  You
probably want -7.1 from here:

https://people.redhat.com/~rjones/libguestfs-winsupport/7/7.1/

In CentOS 7.2, all the required packages will be in the base distro.

You need to use the 'supported' command:

$ guestfish -a /dev/null run : supported
             acl yes
          augeas yes
      blkdiscard yes
blkdiscardzeroes yes
           btrfs yes
        extlinux yes
          fstrim yes
           gdisk yes
            grub no
           hivex yes
         inotify yes
         journal yes
             ldm yes
       linuxcaps yes
     linuxfsuuid yes
    linuxmodules yes
     linuxxattrs yes
            luks yes
            lvm2 yes
           mdadm yes
           mknod yes
          ntfs3g yes
       ntfsprogs yes
        realpath yes
           rsync yes
           scrub yes
         selinux yes
        syslinux yes
          wipefs yes
             xfs yes
