file: Deduplicate speed tradeoff code

The nautilus_file_should_show_thumbnail() method was first introduced
in commit 469047a2a5

It duplicated the tradeoff setting logic that was already present in
get_speed_tradeoff_preference_for_file(), a shared function for both
top left text preview and child directories item count.
(Top left text preview has since been phased out.)

The code duplication grew when support for the filesystem::use-preview
attribute was added in commit 00e59a6b3c

Instead, let's make should_show_thumbnail() use the shared function.
