Treat <x> and <x>_compressed prebuilt APEXes as being equivalent

(cherry picked from commit 1aa50564)

When extracting dex files from prebuilt APEXes the build fails if it
finds two or more prebuilt APEXes that could provide the dex files.
This change treats <x> and <x>_compressed APEXes as being the same
and always selects the uncompressed APEX.
