overlay coreos-base/update_engine: fix build issues with gcc 13

Starting from gcc 13, it is required to explicitly include cstdint, as
other standard library header files will not include other headers that
were being used internally by the library. So update_engine also has to
explicitly include cstdint to avoid build errors.

Pulls in flatcar/update_engine#27
