Rebuild Haystack and Store L3 Keybox in /data/vendor

(This is a merge of http://go/wvgerrit/25900 and http://go/wvgerrit/25920)

This commit contains the latest Haystack prebuilt binaries based on
the latest OEMCrypto code in the Widevine tree. This is to pick up the
change "Report error OEMCrypto_ERROR_ENTRY_IN_USE", which fixes
several failing unit tests. This CL also adjusts the L3 library so
that it stores its data in the directory specified by the layer above.
