Implement system namespace for vendor process
For vendor process default namespace searches as following order: 1. /vendor/lib/(hw|egl), /vendor/lib: Vendor libs + VNDK-vnd-ext 2. /system/lib/vndk-$(ver): VNDK libs 3. /vendor/lib/vndk-sp-$(ver): VNDK-SP-vnd-ext 4. /system/lib/vndk-sp-$(ver): VNDK-SP and searches system namespace (/system/lib) only for LL-NDK libs. This configuarion is used only with BOARD_VNDK_VERSION is defined. Bug: 37192038 Test: build with 'BOARD_VNDK_VERSION=current' and boot Change-Id: If9778b9266a084846ba8fe73e6bff25828359d33
