comment fix in hash-pjw-bare

[Bruno Haible]

Hi,

In lib/hash-pjw-bare.h a comment says that the function's result depends on
the signedness of 'char'. But in fact it does not: the function does not
use the 'char' type at all.

Already reported by Paul in
http://lists.gnu.org/archive/html/bug-gnulib/2012-09/msg00156.html

Here's a suggested comment fix:
