Andy Lutomirski 02e425668f x86/vdso: Fix vDSO syscall fallback asm constraint regression

When I added the missing memory outputs, I failed to update the
index of the first argument (ebx) on 32-bit builds, which broke the
fallbacks.  Somehow I must have screwed up my testing or gotten
lucky.

Add another test to cover gettimeofday() as well.
