make-key: Enforce PBEv1 password-protected signing keys

The bug https://bugs.openjdk.java.net/browse/JDK-8076999 prevents
the usage of PBESv2 key encryption schemes enforced by recent
OpenSSL versions.

So we enforce the PBE-SHA1-3DES scheme as recommended
in https://pthree.org/2013/05/27/strengthen-your-private-encrypted-ssh-keys/
