Raising some of the expected times, as we have seen some random
failures that do not appear to be performance regressions.

The assertion failures were:

    Build_No_Changes: Exceeded expected time of 3250ms, actual 3270ms
    Build_AndroidResource_Change: Exceeded expected time of 4750ms, actual 4770ms
    Build_XAML_Change(True,False): Exceeded expected time of 6250ms, actual 6270ms
    Build_XAML_Change(False,False): Exceeded expected time of 9500ms, actual 9560ms
