installer: final: Delete SQLite WAL and shm files upon completion.
Previously, db.sqlite-{wal,shm} could be left behind after stopping
guix-daemon. When resuming installation, SQLite could end up behaving
as if transactions visible in the WAL file had been committed, in spite
of having restored SAVED-DATABASE.
Fixes <https://issues.guix.gnu.org/59784>.

* gnu/installer/final.scm (install-system): Before restarting
guix-daemon, delete db.sqlite-{wal,shm}.
