Cleanup: misleading/incorrect argument to BLI_path_to_display_name

The strlen() was passed in as a size argument, in this case it
couldn't have caused an overflow because the source & destination
happened to be the same size.

Also reduce the destination buffer size as this is used for an ID name.
