Permit empty passphrase for key by default

As this change might be controversial we both check if
"enforce-passphrase-constraints" is set in the GnuPG backend
and make this option configurable in kleopatrarc.

For most people a passphrase on a key is not really required
since the endpoint is either fully compromised, in which case
a keylogger can obtain the passphrase or the local storage
is secure. The wording "encrypt key with an unrecoverable
passphrase" should also further clarify what happens when
a passphrase is entered.
