Subject: [PATCH] src: update cares_wrap OpenBSD defines

Move the `#define`s back into `cares_wrap.cc`, as they are part of
the implementation, not the declarations used in `cares_wrap.h`,
and apply the suggestion from
https://github.com/nodejs/node/pull/38572#discussion_r627809407
to make the defines a bit more generic and not check for OpenBSD
specifically.
