useradd does not create user mail spool files with setfscreatecon

this requires that i need auto file type transitions from var_spool to user.var_spool_object

unconfineduser does not auto subject type transition when he runs useradd so he needs to create files in var_spool with a auto type transition to user.var_spool_object
this is likely to conflict, although not with rpm since unconfineduser does run rpm with a auto subject type transition
