flounder: make aosp_flounder a t132 device

aosp_flounder is now a t132 device.  aosp_flounder64 is currently
exactly the same, but it will soon become a multilib 64-bit build.

The kernel currently reports hardware flounder64 for t132 flounder
devices, so the init files are copied to both init.flounder.rc and
init.flounder64.rc.  Later only init.flounder.rc will be installed.
