pkg gives the same hash on packages with differing file contents

[cgull]

I found this in my worktree, sitting around since 2021. It extends the conflicts.sh regression test to show a case where packages with differing file contents, but otherwise identical, have the same digest hash. That would seem to be a bug.

I have no memory now of why I coded up this test, but I'm guessing I had a problem with packages like this not upgrading.

I now think pkg query %X <package> is working as intended (it's intended to ignore file contents), and this regression test is wrong.

However, there are many problems around pkg_checksum_generate(), such as the inc_files parameter never being used (it only works by accident because the package database being queried does or doesn't have file records loaded).

@evadot I think I understand your motivations for pkgbase but what about non-base packages that change?

[cgull]

Actually, I may be wrong. I think commit c337c10 is supposed to include files in the checksum. What's the intended behavior with pkg query %X <installed-package>? pkg query -f <uninstalled.pkg> %X? pkg rquery %X <remote-pkg>? (The last fails, and I'm pretty sure it's not supposed to work.)
