Subject: selftests/bpf: Fix endianness issue in sk_assign
Patch-mainline: v5.10-rc1
Git-commit: b6ed6cf4a3acdeab9aed8e0a524850761ec9b152
References: bsc#1177028

server_map's value size is 8, but the test tries to put an int there.
This sort of works on x86 (unless followed by non-0), but hard fails on
s390.

Fix by using __s64 instead of int.
