dockerfile/rpm: Setup new dnf repo with our built content

We do not want to use `--nodeps` for installing our built rpms in the
target-rootfs. So, we create a new dnf repo in `/tmp/localrepo`, copy
our rpms in there and set it's priority as highest.

We pass `--install bootc` to bootc-base-imagectl which will install from
our newly created repo ensuring we have the latest binaries in the final
image
