mkimage: Skip adding non-existent IDs to a list

In show_valid_options(), this patch introduces checking whether
a category has an entry ID. If not, adding it to a list for output
is skipped before calling qsort().
This patch will affect all kinds of image header categories
(-A, -C, -O and -T flags).
