consolidate profiles and profile-cache

Ownership problems originally prevented using the same directory
for /data/dalvik-cache/profiles and /data/dalvik-cache/profile-cache.
Now that ownership is assigned via init.rc, we can consolidate these
two directories.

Old profile files are stored in /data/dalvik-cache/profiles/ with
the "@old" extension. We use "@" instead of "." to avoid conflicts
should someone create a package ending in ".old".
