Subject: [PATCH 1/2] test/makekeys.sh: fix POSIX compliance

Not all shells provide 'echo -e' and using printf is more portable.

One shell that will fail is dash(1).

ssl................... 10/63 FAIL - dname_readable (certificate subject dname was `-e H\0350llo World, Neon Hackers Ltd, Cambridge, Cambridgeshire, GB' not `Hèllo World, Neon Hackers Ltd, Cambridge, Cambridgeshire, GB'
