mkimage: fix display of image types list
Since commit 5b9d44df2307f (mkimage: Display a better list of available image
types) mkimage usage text suggest to "use -T to see a list of available image
types". Unfortunately, commit 02221f29deb8 (mkimage: Convert to use getopt())
broke that feature, because getopt() fails when -T has no option argument.
Add a pseudo image type name 'list' that lists all image types. Update the
usage text accordingly.
