program loading: provide one cache maintenance callback

Instead of having 2 different functions to call when a program
is loaded provide a single callback with flags parameter. The
previous callbacks for cache management routines did this:

for_each_program_segment:
	arch_program_segment_loaded(start, size);
arch_program_loaded();

Now, use one callback instead:
for_each_program_segment:
	arch_segment_loaded(start, size, SEG_FINAL?);
