6918f0b7eb libtests: include cstdint for GCC 15
GCC 15 starts to no longer include this by default, requiring it to be
explicitly included.

Error message:
libtests/cxx11.cc:75:16: error: ‘uint8_t’ was not declared in this scope
   75 |     check_size<uint8_t>(1, false);
      |                ^~~~~~~
libtests/cxx11.cc:10:1: note: ‘uint8_t’ is defined in header ‘<cstdint>’; this is probably fixable by adding ‘#include <cstdint>’
    9 | #include <regex>
  +++ |+#include <cstdint>
   10 | #include <type_traits>
