Avoid absolute path loading .so after M

Bug: 26548955

Some apps have unpacked APKs, e.g., Google Camera. Using absolute path
for shared libraries provided by the app will prevent them from loading.
Fixed this by limiting usage of the absolute path to API levels older
than M.

Updated the bug number comment in the code so that they are clickable.

Bumped the SDK level to 23 for RenderScript support lib build, so that
we can use the proper API level constant defined in
