[PATCH] getifaddrs.3: ATTRIBUTES: Note functions that are thread-safe

[Zeng Linggang]

After research, We think getifaddrs() and freeifaddrs() are not
thread-safe. But, there is not markings of getifaddrs() and
freeifaddrs() in glibc document.
- getifaddrs:  MT-Safe
- freeifaddrs: MT-Safe

The following line would best be omitted. All I'd like to see here is 
what's in the glibc manual.

Re: [PATCH] getifaddrs.3: ATTRIBUTES: Note functions that are thread-safe

> - getifaddrs:  MT-Safe
> - freeifaddrs: MT-Safe
