This is done to enable backup functionality in the admin interface while
we're waiting for the libsqlite-sys 0.17 to bubble up in the upstream
dependencies. Then we can start using `VACUUM INTO`
This also extends the check for the sqlite binary to also try `sqlite3`
as this is the name of the binary in baseimage distributions we use.
This changes the healthcheck to use `sh` instead of bash, that is absent
from some image versions. (like alpine)
It also removes `*mariadb*` packages from runtime image of sqlite images
as these shouldn't be required.
