Subject: [PATCH] tests: fix compilation error for os400

OS400 uses BSD 4.3 setsockopt() prototype by default: this does not
define parameter as const, resulting in an error if actual parameter is
const. Remove the const keyword from the actual parameter cast: this
works in all conditions, even if the formal parameter uses it.

Closes #11547
