Revert^2 "Build dex2oatd with compile_multilib: both."

This reverts commit 9ab73d5d.

apex does not support symlink_preferred_arch so zipapex tests could
not find dex2oatd. This updates the run-test-jar to use dex2oatd64 in
this situation.

Reason for revert: Fixed issue causing linux_bionic to fail with the CL
