GCC: Disable the -Wmissing-field-initializers in GCC 4 

Perfectly valid C++11 code trying to default-initialize an object with
{} is being warned. GCC 5 and up only warn if you initialize some fields
and not others.

qcborvalue.h:68:25: error: missing initializer for member 'QCborError::c' [-Werror=missing-field-initializers]
     QCborError error = {};
                         ^
