bsdacct: fix uid/gid misreporting

Browse Source 
commit d8e180dcd5 "bsdacct: switch
credentials for writing to the accounting file" introduced credential
switching during final acct data collecting.  However, uid/gid pair
continued to be collected from current which became credentials of who
created acct file, not who exits.
