child_process: fix spawn() optional arguments

Spawn's arguments were documented to be optional, as they are for the
other similar child_process APIs, but the code was missing. Result was
`child_process.spawn('node', {})` errored when calling slice() on an
Object, now it behaves as the documentation said it would.

test: fix http-many-ended-pipelines server close

The test was calling server.close() without waiting for the server
to have received all the requests. This would cause an ECONNRESET.
test: fix http-incoming-pipelined-socket-destroy

The test was calling server.close() after write on the socket
had completed. However the fact that the write had completed was
not valid indication that the server had received the data.

This would result in a premutaure closing of the server and
an ECONNRESET event on the client.

fix #6933
deps: backport b5135bbc from c-ares repo

Original commit message:

    ares_parse_txt_reply: return a ares_txt_reply node for each sub-string

    Previously, the function would wrongly return all substrings merged into
    one.
