Bug 1476914 - Add fuzzy-if on Bug 1443902's reftests for Android. r=masayuki

Android's reftest of Bug 1443902 is failed rarely (Bug 1476914, Bug 1475049
Bug 1477502 and Bug 1476129) due to "image comparison, max difference: 1,
number of differing pixels: 1". But I don't know why difference is 1 and
I think that this might be reftest framework for Android or Android emulator
issue.

So I would like to add fuzzy-if as workaround.
