Fix list_features to include space after first feature (#10711)

Regressed in e134cc9d4a: the use of list_in_columns was not adding a
space after the first features, because we do not start on a new line:

> Features: -acl+iconv +tui

This moves all the related code to `list_features`, and just joins them
with spaces.
