Allow OEMCrypto v8 or v9

Browse Source 
From Widevine CL:
https://widevine-internal-review.googlesource.com/#/c/9184/

This is some shim code that will load either an OEMCrypto
version 8 or version 9 library.  This should allow us
to test and run stable devices until all OEM's have
updated to version 9.

Android Level 3 library versions are:
level3/mips/libwvlevel3.a  Level3 Library Feb 27 2014 18:18:34
level3/x86/libwvlevel3.a  Level3 Library Feb 27 2014 18:22:14
level3/arm/libwvlevel3.a  Level3 Library Feb 27 2014 12:31:29
