init_parse_tree() now takes ownership of lhost and shost, if any.

Browse Source 
This means that lhost and shost in struct sudoers_parse_tree
are no longer const and that free_parse_tree() will free lhost/shost.
The only consumer that passed in lho.st/shost was the SSSD back-end
which has been updated to avoid a double-free.
