Previously handling of DISSECT_IMAGE_MKDIR was pretty weird and broken:
it would control both if we create the top-level mount point when
mounting an image, and the inner mount points for images that consist of
multiple file systems. However, the latter is redundant, since
1f0f82f131 does this too, a few lines
further up – unconditionally!
Hence, let's make the meaning of DISSECT_IMAGE_MKDIR more strict: it
shall be only about the top-level mount point, not about the inner ones
(where we'll continue to create what is missing alwayway). Having a
separate flag for the top-level mount point is relevant, since the mount
point dir created by it will remain on the host fs – unlike the
directories we create inside the image, which will stay within the
image.
This slightly change of meaning is actually inline with what the flag is
actually used for and documented in systemd-dissect.
