pixman-bits-image: fix -Walloc-size

GCC 14 introduces a new -Walloc-size included in -Wextra which gives (when forced
to be an error):
```
../pixman/pixman-bits-image.c: In function ‘create_bits’:
../pixman/pixman-bits-image.c:1273:16: error: allocation of insufficient size ‘1’ for type ‘uint32_t’ {aka ‘unsigned int’} with size ‘4’ [-Werror=alloc-size]
 1273 |         return calloc (buf_size, 1);
      |                ^~~~~~~~~~~~~~~~~~~~
```

The calloc prototype is:
```
void *calloc(size_t nmemb, size_t size);
```

So, just swap the number of members and size arguments to match the prototype, as
we're initialising 1 element of size `buf_size`. GCC then sees we're not
doing anything wrong.
