tests: improve new ascii test of dd

Browse Source 
* 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.
