search for pkg names in the cache case-sensitive

Package names have to be lowercase (debian-policy §5.6.1) and in as
lowlevel as these method are it would be quiet strange to treat an
invalid package "suddently" as a valid one which other tools might or
might not accept. If case-insensitivity is really needed the frontend
should ensure this rather than these methods waste cpu cycles by
default.
