fuse: truncate on spontaneous size change
Memory mappings were only truncated on an explicit truncate, but not when the
file size was changed externally.
Fix this by moving the truncation code from fuse_setattr to
fuse_change_attributes.
Yes, there are races between write and and external truncation, but we can't
really do anything about them.
