pactree: carry a list of databases for dep resolution
Declare an alpm_list which, for now, only holds our local database.
walk_deps and walk_reverse_deps are refactored to account for this, and
a helper function is added to wrap alpm_db_get_pkg for traversing a
list.
This is groundwork for letting pactree walk the sync DBs.
