pathname.rb: Pass -s to du instead of -d0

Browse Source 
The option `du -s` is equivalent to `du -d0`. The former is a POSIX standard
(IEEE Std 1003.1-2008), whereas the latter is a BSD extension.

From the BSD man page:
`-s Display an entry for each specified file. (Equivalent to -d 0)`

From SUSv4:
`-s Instead of the default output, report only the total sum for each of the specified files.`

Closes Homebrew/homebrew#16516.
