Modify installd's restorecon function.

Changes above with PMS and below with libselinux
have resulted in a few changes to the restorecon data
api. This change is needed in order to support the new
way to issue a recursive restorecon of certain
/data/data directories.

The restorecondata function has also been modified to
find all users on the device for a given package name
(argument to the function) and to issue a separate
recursive restorecon call for each.
