Create secondary dex profiles relative to the provided dex path

Create secondary dex profiles relative to the provided dex path

We previously used the realpath to simplify the validation and processing
in installd. However it ended up making things more complicated when
cleaning up the profiles, especially because of /data/user/0 symlinks to
/data/data/.

Instead of using the realpath of the dex file to compute the profile
location, use the file path as given. This makes things consistent with
DexManager registration and allows for easier dex file reconciliation in
the presence of symlinks.
