package/ledmon: add upstream patch to fix build w/ gcc-14

Add an upstream patch to fix a build issue related to uint64_t:

utils.c: In function ‘get_uint64’:
utils.c:118:18: error: passing argument 1 of ‘str_toul’ from incompatible pointer type [-Wincompatible-pointer-types]
  118 |         str_toul(&defval, p, NULL, 16);
      |                  ^~~~~~~
      |                  |
      |                  uint64_t * {aka long long unsigned int *}
In file included from utils.c:48:
utils.h:412:29: note: expected ‘long unsigned int *’ but argument is of type ‘uint64_t *’ {aka ‘long long unsigned int *’}
