package/optee-client: fix build with gcc 4.8

Fix the following build failure with optee-client 3.11.0 and gcc 4.8:

/home/giuliobenetti/autobuild/run/instance-2/output-1/build/optee-client-3.11.0/libckteec/src/pkcs11_processing.c: In function 'ck_create_object':
/home/giuliobenetti/autobuild/run/instance-2/output-1/build/optee-client-3.11.0/libckteec/src/pkcs11_processing.c:22:9: error: missing initializer for field 'buffer' of 'struct serializer' [-Werror=missing-field-initializers]
  struct serializer obj = { };
         ^

Build failure is raised since version 3.10.0 and
