qemu-ga: Fix missing environ declaration

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

This worked for me because on F16 environ is declared in <unistd.h>, but
that doesn't happen in OpenBSD for example, causing a build failure.

This commit fixes the build error by declaring environ if it hasn't
being declared yet.

Also fixes a build warning due to a missing <sys/wait.h> include.
