minifi-cpp: add missing <cstdint> include for int64_t on musl

StreamCallback.h uses int64_t without including <cstdint>, relying on
a transitive include that only exists on glibc.

+Subject: [PATCH] StreamCallback.h: add missing <cstdint> include for
+ int64_t
+
+StreamCallback.h uses int64_t in ReadWriteResult and in the
+InputStreamCallback/OutputStreamCallback std::function aliases, but
+never includes <cstdint> itself. On glibc/libstdc++ this happens to
+compile because some other transitively-included standard header
+provides int64_t first, but musl's libc++ headers do not provide
+this transitive declaration, so the header fails to parse with
+"unknown type name 'int64_t'" (which then cascades into std::function
+template errors). This is the same class of issue already fixed for
+LibWrapper.h and RepositoryMetricsSource.h by
+0001-Fix-build-with-gcc-16.patch; StreamCallback.h needs the same
+treatment.
