deps: use nghttp2's config.h on all platforms

[sam-github]

Fix warnings about use of htonl(), etc. by including config.h for all
platforms, defining HAVE_ARPA_INET_H on non-Windows, and therefore
including <arpa/inet.h>, which defines the host to network byte order
conversion functions.

--

This works on Linux, I'll see what ci says about the other platforms.

Unrelated?

[sam-github]

Should not be related, I wrote that test in #27157, and it passed there, except travis's CI state isn't visible anymore.

I found some other recent travis jobs that include #27157, and they passed, like https://travis-ci.com/nodejs/node/builds/108825880

I rebased against master, and repushed.
