handle arches that are missing dexdump in tests

Browse source 
dexdump is only available for certain CPU architectures.  Google binaries
are for amd64 and arm64.  Debian binaries are for amd64, arm64, armhf,
i386, and riscv64.  That leaves out armel, ppc64el, s390x, loong64, etc.
where pure Python code runs perfectly fine.
