glpk: fix build with gcc15

- add patch from debian replacing `bool` typedef and `true`/`false`
defines with `#include <stdbool.h>`:
https://sources.debian.org/data/main/g/glpk/5.0-2/debian/patches/gcc-15.patch

Upstream issue:
https://lists.gnu.org/archive/html/bug-glpk/2025-05/msg00000.html
(recommends to use `CFLAGS="-ansi"` instead)

Fixes build failure with gcc15:
```
In file included from api/minisat1.c:23:
./minisat/minisat.h:37:13: error: 'bool' cannot be defined via 'typedef'
   37 | typedef int bool;
      |             ^~~~
./minisat/minisat.h:37:13: note: 'bool' is a keyword with '-std=c23' onwards
./minisat/minisat.h:37:1: warning: useless type name in empty declaration
   37 | typedef int bool;
      | ^~~~~~~
```
