Subject: test: adjust expecting error for getaddrinfo() under EMFILE
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=4ffc7116177230ad2b8b94d51bbf89a14dc83687;p=libevent

test: adjust expecting error for getaddrinfo() under EMFILE

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.
