concepts-manual: Updated Image Generation section.

Added wording to note that the rootfs might be compressed
depending on the IMAGE_FSTYPES setting, which would have to
actually do compression.  Also, fixed examples of "do_image_type"
and "do_image_ext4" so that there is no "[depends]" as part
of the example.

variable.
The process turns everything into an image file or a set of
image files and compresses the root filesystem image to
image files and can compress the root filesystem image to
reduce the overall size of the image.
The formats used for the root filesystem depend on the
<filename>IMAGE_FSTYPES</filename> variable.
Compression depends on whether the formats support
compression.
