samldb: Address birthday paradox adding an RODC
It is possible that the randomly chosen RODC number will be one
that is already in use. The samldb_krbtgtnumber_available()
function was meant to prevent that, but due to a typo did not.
There is no other race here as the whole thing is inside a transaction,
and we have duplicate protection on samAccountName, so the failure
looked like this:
