getaddrinfo.3: Note that 'errno' is set in parallel with EAI_SYSTEM 

The previous wording wasn't very explicit, leaving room for
believing that 'errno' may be 0 after returning EAI_SYSTEM.

Use a wording similar to other pages, for added consistency.

[mtk: edited commit message title; also, POSIX notes that
'errno' is set in this case.]
