package/libargtable2: fix build error with gcc-14

Browse Source 
The following build error is happening on the autobuilder:

```
arg_int.c:60:12: error: implicit declaration of function 'isspace' [-Wimplicit-function-declaration]
   60 |     while (isspace(*ptr))
      |            ^~~~~~~
arg_int.c:33:1: note: include '<ctype.h>' or provide a declaration of 'isspace'
   32 | #include <limits.h>
  +++ |+#include <ctype.h>
   33 |
arg_int.c:89:8: error: implicit declaration of function 'toupper' [-Wimplicit-function-declaration]
   89 |    if (toupper(*ptr++)!=toupper(X))
      |        ^~~~~~~
arg_int.c:89:8: note: include '<ctype.h>' or provide a declaration of 'toupper'
```

Both `isspace` and `toupper` are declared in the `ctype.h` header.
This build error started to happen with gcc-14.
The `ctype.h` include was added in a later upstream commit.
This patch adds that upstream commit and strip everything else to only
patch that include.
