gfs2-utils: master - libgfs2: Support the new dirent de_cookie field

It also seems that meta.c was not using the GFS2_HAS_* defines from clusterautoconfig.h and that was causing a unit test to fail with gfs2_dirent: __pad: offset is 28, expected 26 gfs2_dirent: size mismatch between struct 40 and fields 38 This commit adds an #include to fix that.
