Verify 'W_EXITCODE' only when we provide our own definition.

Browse source 
Fixes <https://bugs.gnu.org/60971>.
Reported by lloda <lloda@sarc.name> and Greg Troxel <gdt@lexort.com>.

On macOS and NetBSD, 'WEXITSTATUS' expects an lvalue so the expression
passed to 'verify' would be invalid.

* libguile/posix.c: Move 'verify' assertion within #ifdef.
