x86_32, signal: Fix vdso rt_sigreturn

        x86, vdso: Reimplement vdso.so preparation in build-time C

Contained this obvious typo:

-               restorer = VDSO32_SYMBOL(current->mm->context.vdso, rt_sigreturn);
+               restorer = current->mm->context.vdso +
+                       selected_vdso32->sym___kernel_sigreturn;

Note the missing 'rt_' in the new code.  Fix it.
