Parent's canonical path; not parent of canonical

When moving from SD card to internal, the PackageManager should check if
the native library directory parent's canonical path matches the
canonical data directory.

However, it was checking the canonical native library directory's
parent matches the data directory which makes tests concerning moving
from SD card to internal storage fail.
