FindHDF5: Fix regression in providing HDF5_IS_PARALLEL

Since commit v3.6.0-rc1~85^2 (HDF5: Refactor the use of compiler
wrappers, 2016-04-01) we have additional code paths that find HDF5 and
suppress the original search logic.  Report HDF5_IS_PARALLEL from these
other code paths too.

Closes: #16257
