Refactor sanitized library on-disk layout - Make.

Browse source 
This CL moves the location of ASAN-ified libraries on disk in the
following manner:
/data/lib* --> /data/asan/system/lib*
/data/vendor/* --> /data/asan/vendor/*

There are a couple of advantages to this, including better isolation
from other components, and more transparent linker renaming and
SELinux policies.

Bug: 36574794
Bug: 36674745
Test: m -j40 && SANITIZE_TARGET="address" m -j40 and the device
boots. All sanitized libraries are correctly located in /data/asan/*.
