vim-patch:342ae5f: runtime(progress): Use setlocal for expandtab

The Progress syntax file gained `set expandtab` in 4c3f536f4 (updated
for version 7.0d01, 2006-04-11). The Progress language itself doesn't
distinguish between tabs and spaces for indentation, so this seems like
something that should be left to user preference; but the setting is
accompanied by the comment "The Progress editor doesn't cope with tabs
very well", so there may be reason to keep it.

However, using `set` means that any new buffers created after editing a
Progress file will also have `expandtab` turned on, which is likely
contrary to a user's expectations. We should use `setlocal` instead to
avoid this.
