Make QSslError hashable for Qt <= 5.4.

Browse Source 
PyQt uses qHash() for __hash__, and qHash for QSslError was added with Qt 5.4.

This means 2da45e98ca raised TypeError there as
QSslError is unhashable.

For those older Qt versions, we implement __hash__ ourselves which does about
the same thing as Qt does, combining the DER (binary) representation of the
certificate and the error() (which is just a QEnum, hashable as int).
