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.
