Gave two kBubbleReshowsHistogramName unique names

In jumbo builds many cc files are compiled together in the same
translation unit. When that happens, those files will share the
same anonymous namespace so if they use symbols of the same name
they will clash.

That happened with two kBubbleReshowsHistogramName constants in
chrome/browser/ui/exclusive_access and this patch gives
those two more unique names.
