dolthub/dolt#10136: Fix dolt_backup to work in non-Dolt directories

[elianddb]

Fixes #10136

• Fix dolt_backup to work in non-Dolt directories; this amends the dolt.go boolean expression for commands that accept non-Dolt directories into a searchable map.
• Remote sql-backup.bats from local-remote.bash so it also gets run against server.

This change looks good from the perspective of testing and the features behavior.

I think you may want to ship this as it's own change. As discussed in DM, the abstractions for determining when it's ok to not have a physical dolt database as a file accessible entity are busted. Fixing that would be greatly appreciated.
