test: adjust expecting error for getaddrinfo() under EMFILE

Browse Source 
When getaddrinfo() cannot allocate file descriptor glibc/musl-libc on
linux report EAI_SYSTEM error. But this is not true for freebsd libc [1]
(and hence apple libc [2]), they report EAI_NONAME error instead, so
adjust expectation.
