tools/mkimage: Print FIT image contents after creation

Previously, there was no indication to the user that a FIT image was
successfully created after executing mkimage.  For example:

  $ mkimage -f uImage.its uImage.itb
  DTC: dts->dtb  on file "uImage.its"

Adding some additional output after creating a FIT image lets the user
know exactly what is contained in their image, eg:

  $ mkimage -f uImage.its uImage.itb
  DTC: dts->dtb  on file "uImage.its"

This brings the behavior of creating a FIT image in line with creating a
standard uImage, which also prints out the uImage contents after
creation.
