If hcoll fails to create mpi derived type let's set zero_dte on this dtype.
This will save cycles on subsequent collective calls with the same derived
type since we will not try to create hcoll type again.

The ompi_datatype_get_single_predefined_type_from_args() recurses down
into a constructed type to identify what base datatype it's built from
if it's built from a single type. But if the type has MPI_LB/MPI_UB,
for example
lens[0] = 1;
lens[1] = 1;
disps[0] = 0;
disps[1] = 0;
types[0] = MPI_LB;
types[1] = MPI_INT;
MPI_Type_create_struct(2, lens, disps, types, &mydt);
then this function will see the base type MPI_LB as differing from MPI_INT
and will identify mydt as not being constructed from a single base type, so
the type will be rejected for calls like MPI_Accumulate.
I think those "meta data" types shouldn't result in rejection like that, and
the above mydt should still be identified as having a single base type
of MPI_INT.
Addition: boslica wanted another change discussed here
https://github.com/open-mpi/ompi/pull/3609
relating to the calculation for "count" after identifying the
predefined_type that was being used.

The nightly tarball scripts have been moved to the ompi-scripts
repo (and rewritten), so are no longer needed in the ompi
repo. Clean up some bits to make life a bit less confusing.

If Open MPI is configured with CUDA, then user also should be using a CUDA build of
PSM2 and therefore be setting PSM2_CUDA environment variable to 1 while using
CUDA buffers for transfers. If we detect this setting to be missing, force set
it. If user wants to use this build for regular (Host buffer) transfers, we
allow the option of setting PSM2_CUDA=0, but print a warning
message to user that it is not a recommended usage scenario.
