Fix outpput of dumpsys package

`dumpsys package` intends to print user state attributes as one line and
then additional install state with additional indentation on new lines.
In ag/24359877 we added an additional quarantine user state that ended
up getting prefixed to the install reason line:

User 0: ceDataInode=1919 ...
 quarantined=false      installReason=0
    firstInstallTime=2023-08-04 15:14:41
    uninstallReason=0

This led to CTS failures where the tests depended on the output of `adb
shell dumpsys package`, in particular anything using `bedstead` with
instant apps.

This change restores the proper line separation and splits out the code
with a comment to help avoid breaking the output again in the future:

User 0: ceDataInode=1919 ... quarantined=false
    installReason=0
    firstInstallTime=2023-08-04 15:14:41
    uninstallReason=0
