[PATCH 6/8] image: Do not #if guard board_fit_config_name_match() prototype

There's no point in guarding function prototypes with #ifdefs. If a
function is not defined, the linker will notice. Having the prototype
does not affect code size.

What the #if guard takes away is the ability to use IS_ENABLED:

	if (CONFIG_IS ENABLED(FIT_IMAGE_POST_PROCESS))
		board_fit_config_name_match(...)

When the prototype is guarded, the above form cannot be used. This
leads to the proliferation of #ifdefs, and unreadable code. The
opportunity cost of the #if guard outweighs any benefits. Remove it.
