Audio VTS: Allow 4GB buffer prepareToWrite/Read to succeed on 64 bits

Because on oc-dev the runtime image can not be modified and that this is
not a bug but a test and implementation misalignment,
allow prepareForWrite/Read(UINT32_MAX, UINT32_MAX) to succeed on oc-dev.

MR1 will have a better fix where the HAL will always reject > 1GiB
buffers independently of the architecture.

Test: vts-tradefed run commandAndExit vts --module VtsHalAudioV2_0Target
Bug: 67030516
