TOOLS: don't overwrite config.ldb

This partially reverts d2d8f34
There should be no reason for 'sssctl' to run if SSSD itself isn't
running (ir wasn't run so 'config.ldb' is absent).

Enforced recreation of 'config.ldb', on the other hand, might spoil
file ownership, as 'sssct' is typically run under 'root', but SSSD
itself might running under 'sssd' user.
