Subject: [PATCH] Add #include <stdint.h> to fix building with gcc 15

With gcc 15, the C++ Standard Library no longer includes other headers
that were internally used by the library. In herbstluftwm's case the
missing header is <stdint.h>

Downstream Gentoo bug: https://bugs.gentoo.org/937529

Closes: #1612
