Subject: [PATCH] qemu-ga: Fix missing environ declarion

Commit 3674838cd05268954bb6473239cd7f700a79bf0f uses the environ
global variable, but is relying on it to be declared somewhere else.

This works for Linux because _GNU_SOURCE declares it, but it brakes
for system where _GNU_SOURCE is not declared, such as OpenBSD.

Fix it by declaring environ when _GNU_SOURCE is not defined.
