ls-tree: `-l` should not imply recursive listing

In 9c4d58ff2c (ls-tree: split up "fast path" callbacks, 2022-03-23), a
refactoring of the various read_tree_at() callbacks caused us to
unconditionally recurse into directories if `-l` (long format) was
passed on the command line, regardless of whether or not we also pass
the `-r` (recursive) flag.

Fix this by making show_tree_long() return the value of `recurse`,
rather than always returning 1. This value is interpreted by
read_tree_at() to be a signal on whether or not to recurse.
