There's two different paths through the sigreturn code, depending on whether the VDSO is mapped or not. We recently discovered a bug in the unmapped case, because it's not commonly used these days. So add a test that sends itself a signal, then moves the VDSO, takes another signal and finally unmaps the VDSO before sending itself another signal. That tests the standard signal path, the code that handles the VDSO being moved, and also the signal path in the case where the VDSO is unmapped.
