selftests/seccomp: Use bitwise instead of arithmetic operator for flags



This silences the following coccinelle warning:

"WARNING: sum of probable bitmasks, consider |"

tools/testing/selftests/seccomp/seccomp_bpf.c:3131:17-18: WARNING: sum of probable bitmasks, consider |
tools/testing/selftests/seccomp/seccomp_bpf.c:3133:18-19: WARNING: sum of probable bitmasks, consider |
tools/testing/selftests/seccomp/seccomp_bpf.c:3134:18-19: WARNING: sum of probable bitmasks, consider |
tools/testing/selftests/seccomp/seccomp_bpf.c:3135:18-19: WARNING: sum of probable bitmasks, consider |
