Remove /data/dalvik-cache/profiles from domain. Profiling information
leaks data about how people interact with apps, so we don't want
the data to be available in all SELinux domains.

Add read/write capabilities back to app domains, since apps need to
read/write profiling data.

Remove restorecon specific rules. The directory is now created by
init, not installd, so installd doesn't need to set the label.
