ibrdtn: Fix include for stricter GCC 4.4 header handling

GCC 4.4 is stricter on its headers so we need to make sure the uint64_t is
really available or the compiler errors out:
src/data/BlockFactory.cpp:101: error: ‘uint64_t’ was not declared in this scope
src/data/BlockFactory.cpp:101: error: expected ‘;’ before ‘i’
src/data/BlockFactory.cpp:101: error: ‘i’ was not declared in this scope
