Handle null pkgcache for local/sync db_populate()

In sync_db_populate() and local_db_populate(), a NULL db->pkgcache is not
caught, allowing the functions to continue instead of exiting.

A later alpm_list_msort() call which uses alpm_list_nth() will thus traverse
invalid pointers in a non-existent db->pkgcache->list.

pm_errno is set to PM_ERR_MEMORY as _alpm_pkghash_create() will only return
NULL when we run out of memory / exceed max hash table size. The local/sync
db_populate() functions are also exited.
