* tests/dd/ascii.sh: Quote so that '\\' is passed
to printf rather than a single '\', as that's not portable.
bash, dash, zsh and external solaris printf were seen to support
printf '\%03o' 1 2
while ksh, freebsh shell and external GNU printf need the more portable
printf '\\%03o' 1 2
Note we don't use env here to call the coreutils printf implementation,
as there are many printf calls, so relying on portable shell
implementations will be faster.

* tests/dd/ascii.sh: Avoid unnecessary subshells. Catch dd's
exit code. Remove testing artifact. In the case of a comparison
failure, show the differences in octal format in addition to
"binary files differ". Simplify the creation of the 'in' file.
