Disable browser hit testing tests on Android

Browser process hit testing was enabled on Android in r455559, along
with the appropriate browser tests. Unfortunately on some builders these
tests fail, due to coordinates being off skewed from expectations. The
tests attempt to account for scale factor rounding error on Android that
does not exist on other platforms, due to differently treatment of DSF,
but apparently the variance can be quite high across devices. We need
to investigate a way to work around this in browser tests.
