libzoned: use blk_zone_v2 and blk_zone_report_v2 by default

Old blk_zone and blk_zone_report should be compatible with v2.
And, old blk_zone_report uses reserved[4] which breaks the build.

struct blk_zone_report {
	__u64		sector;
	__u32		nr_zones;
	__u8		reserved[4];
	struct blk_zone zones[0];
};
