[mutter/wip/smcv/issue2065] Consistently pass timestamp as uint64 when creating MetaStartupSequence

[Simon McVittie <smcv src gnome org>]

commit e1dd1d974bbd64dc42c1916925a10464e640697f

    Consistently pass timestamp as uint64 when creating MetaStartupSequence
    
    Passing the wrong type to a varargs function can cause a mismatch
    between marshalling and unmarshalling on the stack, particularly on
    32-bit architectures. This results in a build-time test failure.
