[PATCH] images: remove unused FIT.ITS rule

[Ahmad Fatoum]

The rule building a FIT image from an .its file has had no users since
commit 7269ad4be96b ("ARM: k3: remove beagleplay FIT image").

Since the kbuild sync with Linux v6.17 moved dtc-tmp into
scripts/Makefile.dtbs, which isn't included for images/, the rule also
passes an empty file name to both the preprocessor and mkimage.

Remove the rule along with its .gitignore entry instead of fixing it.
