extract_utils: Use vdexExtractor for extracting oreo classes.dex

Browse Source 
vdexExtractor is a tool made by anestisb that is written in C++
with code taken directly from art. However, anestisb has also added
a quicken decompiler to oatdump that was merged upstream, so we only
need vdexExtractor for 8.1 and 8.0.
