After updated the latest command line tools, I got int conversion errors.
These should be generated using POSIX version of strerror_r and needless flb_free calling.

The latter one is able to be confirmed with:

 % leaks -atExit -- bin/flb-it-utils test_flb_utils_get_machine_id
 flb-it-utils(34841) MallocStackLogging: could not tag MSL-related memory as no_footprint, so those pages will be inc
luded in process footprint - (null)
 flb-it-utils(34841) MallocStackLogging: recording malloc and VM allocation stacks using lite mode
 Test test_flb_utils_get_machine_id...           [ OK ]
 SUCCESS: All unit tests have passed.
 Process 34841 is not debuggable. Due to security restrictions, leaks can only show or save contents of readonly memo
ry of restricted processes.

out_size is just for used to return the lentgth of ID string.
Removing this flb_free does not cause memory leaks.

```

(I am glad I resisted to upgrade command line tools XD )

I was able to build it on macOS without any warnings or errors in src/flb_network.c.
