ledmon: fix building on 32-bit x86

Building the recipe on x86 platform fails with the following error:
| ../../git/src/utils.c: In function 'get_uint64':
| ../../git/src/utils.c:105:18: error: passing argument 1 of 'str_toul' from incompatible pointer type [-Wincompatible-pointer-types]
|   105 |         str_toul(&defval, p, NULL, 16);

Upstream has already changed this function to avoid overflow due to the
size difference in the pointer - this change backports that patch.

+Subject: [PATCH] Correct get_uint64
+
+For large integer values, the existing implementation will be
+incorrect.
+
+The current implementation of converting strings to integer values
+uses a signed integer for the intermediate conversion and performs
+a range check. Since any value in an unsigned 64-bit integer is valid,
+the range check seems unnecessary. To mimic the same code path, we would
+need a larger integer type.
