[PATCH] arpa/inet: fix mingw compilation warning

[Eric Blake]

Mingw doesn't have <arpa/inet.h>, so a conditional use of
warning about duplicate declarations under -Wredundant-decls.
Making the #pragma unconditional (as was already done in at
least fcntl.in.h) shuts up gcc.

* lib/arpa_inet.in.h (system_header): Hoist to be unconditional.
Reported by Matthew Bolte.

I'm working on a followup patch to make all remaining replacement
headers consistently place #pragma GCC system_header first,
before any include guards, but ran out of time today.  Once that
is done, I'll post it and push along with this one.
