Some restructuring of the build was required to support the different

OEM security levels used on tuna vs stingray & crespo. This is part of
the work for b/4598045 Implementing secure video path on TI OMAP4 chip
for ICS.

The Widevine libraries included here, 4.5.0.4321 also contain a fix
for b/4400696 Pinning and unpinning multiple movie for download behavior
is not uniform for multiple tries.
