status_set_cancelled: fix F08 binding

The F08 bindings for MPI_STATUS_SET_CANCELLED incorrectly had the
"flag" dummy parameter set as INTENT(OUT) when it really should be
INTENT(IN).

On the one hand, this is technically an ABI change.  On the other
hand, this is an incorrect MPI binding.  On the other hand (that's 3
hands for you fans counting at home), this is such a rarely-used API
-- even in the C bindings -- that I'm guessing no one is using this
API, and therefore no one has noticed this error and it isn't worth
porting back to the release branches.
