selftests/x86: Add a missing .note.GNU-stack section to thunks_32.S

[ Upstream commit f706bb59204ba1c47e896b456c97977fc97b7964 ]

test_syscall_vdso_32 ended up with an executable stacks because the asm
was missing the annotation that says that it is modern and doesn't need
an executable stack. Add the annotation.

This was missed in commit aeaaf005da1d ("selftests/x86: Add missing
.note.GNU-stack sections").
