HaikuDepot: Set package state when loading single package

Without this, even installed packages still get an "Install" button.

Fixes #14821.

This was implemented by adding BPackageRoster::IsPackageActive. I decided to
have this take a location since GetActivePackages also did, but as noted in my
TODO comment, I think this is awkward.

It would also be nice to show the user they have a different version of a
particular package, but that would require some changes to IsPackageActive.
