[Buildroot] [PATCH] package/dump1090: fix build with GCC 14

[Peter Korsgaard <peter@korsgaard.com>]

Fixes http://autobuild.buildroot.net/results/1d5804974153f96e80f5200793ec8cd12c9fa18a/

GCC 14 complains if the arguments to calloc (nmemb, size) are swapped
around, causing a build failure as dump1090 builds with -Werror:

net_io.c:107:34: error: 'calloc' sizes specified with 'sizeof' in the earlier argument and not in the later argument [-Werror=calloc-transposed-args]
  107 |     if (!(service = calloc(sizeof(*service), 1))) {

Add a patch from an upstream pull request to fix that.
