Bug 1225202, part 1 - Move some variables earlier in test_fileapi_slice.html. r=baku

Browse Source 
imageLoadHandler, testBinaryData, fileData and size are used by all of
the subtests, so move their declarations earlier so they will remain
at the global scope when we start splitting scopes in preparation for
supporting asynchronous file creation.

memFile is only used in one subtest, so move it later.

code earlier that we want at the global scope
also move memFile down, which we don't want at the global scope
