fix macro define for freeaddrinfo with asyncns previously, this define was only made in lm-asyncns-resolver.c, which does not propagate it to lm-resolver.c, where freeaddrinfo() is used. this means that when asyncns support is used, the standard libc freeaddrinfo() is called on an addrinfo acquired from asyncns_getaddrinfo, which is undefined behaviour, and leads to a segfault on musl libc.
