Make alpm_db_set_pkgreason() arguments more sane

Browse Source 
This can only ever operate on the local database, and a local package at
that. Change the function signature to take a handle and package object,
add the relevant asserts, and ensure the frontend can detect the package
not found condition when finding packages to pass to this method.
