Subject: [PATCH] libpriv/core: Always call rpmtsSetRootDir()

Call `rpmtsSetRootDir()` even in the `JUSTDB` run. This brings us in
line with libdnf and the rpm CLI itself, which both unconditionally call
`rpmtsSetRootDir()` regardless of whether we're targeting the system
root or a subdir.

This doesn't cause a `chroot()` to happen since librpm only does this
if the target root dir is not `/`.

Closes: #1492
