sys-fs/zfs and friends: bump to 0.6.5.2

Upstream release notes:

https://github.com/zfsonlinux/zfs/releases/tag/zfs-0.6.5.2

Some additional improvements were made to the ebuilds in this bump.

1. The incorrect requirement on BLK_DEV_LOOP was removed from sys-fs/zfs-kmod
in favor of a cups ebuild style warning in sys-fs/zfs when BLK_DEV_LOOP is not
avaliable and the test suite has been installed.

2. The regression where we remove the dracut module has been fixed.

3. The failure to migrate users to the zfs-zed script from the zed script has
been fixed.

4. The 9999 ebuilds have been synchronized with the 0.6.5.2 ebuilds.

5. The sys-fs/zfs-kmod-0.6.5 has been removed due to the regression that
prompted sys-fs/zfs-kmod-0.6.5-r1.
