Call `org-clock-in' passing it an explicit argument that corresponds to
the prefix arg value.  (I don't have the function info, but if you do
`C-h f' you should see what the signature is.)

Sometimes a function does not pass the prefix arg as a parameter, but
typically functions do, and the advice above should be sufficient.
