image_types.bbclass: use mke2fs -d to create the ext2/3/4 image
We used populate-extfs.sh which invoked the debugfs to create the image,
now the mke2fs' option "-d root-directory" can do the same thing, and
which is more faster, for example, the core-imag-sato:
* In the past:
$ time mke2fs -t ext4 rootfs.ext4
real 0m0.249s
user 0m0.036s
sys 0m0.132s
$ time populate-extfs.sh /path/to/rootfs/ rootfs.ext4
real 0m29.355s
user 0m10.637s
sys 0m5.544s
* Now:
$ time mkfs.ext4 -F -d /path/to/rootfs/ rootfs.ext4
real 0m6.338s
user 0m3.824s
sys 0m1.356s
More than 25 seconds are saved.
