Use wc to calculate file sizes

Milton pointed out that for the du command the -b and -k options aren't
really compatible. From the man page:

       -b, --bytes
              equivalent to '--apparent-size --block-size=1'

       -k     like --block-size=1K

As a result 'du -bk' will act as if the following args were
used:
	--apparent-size --block-size=1K

However, it's probably not safe to assume this. Fix this by replacing the
use of du with "wc -c". POSIX requires that wc -c prints size of each
input file in bytes so it should be safe (and portable).
