Replace { } initializer by { 0 } to fix the following build failure with
gcc 4.8:

libckteec/src/pkcs11_processing.c: In function 'ck_create_object':
libckteec/src/pkcs11_processing.c:22:9: error: missing initializer for field 'buffer' of 'struct serializer' [-Werror=missing-field-initializers]
  struct serializer obj = { };
         ^
