borgmatic: stage SQLite dump beside source DB (minimal images lack /tmp)

Prev Next 
The helper wrote its staging copy to /tmp, but minimal nix images (mealie)
have no /tmp, so the dump failed 'unable to open database file'. Write it
next to the source DB instead (always on a writable volume); works for any
image, shower included.
