v2writable: cleanup SQLite handles on --xapian-only

I'm not sure exactly why this is needed with run_script
localizing %SIG and everything else, but explictly cleaning up
seems to fix the occasional test failures I see.

Followup-to: 4c6c853494b49368 ("tests: show lsof output on deleted-file-check failures")
