chroot-install: clean downloaded packages

Downloaded packages can consume rather large amounts of space (more than
2GB in some cases). By removing them early, we may be able to avoid
writing them to a physical disk reducing the load imposed by the test.
The major use case is running chroot-installations on tmpfs.
