Use previous ecc workaround for R16B02 as well

The implementation of elliptic-curve ciphers that has been introduced in
R16B01 is still incomplete (and broken).  This makes our previous
workaround (see c0c09a1311) work for R16B02 as well.
Merge branch 'broken-ecc-workaround-R16B02' of git://github.com/KlausTrainer/ranch
