[svn-r8501] Purpose:

Improvement


Description:
The MPI atomicity and file_sync tests may hang if a filesystem
is not able to support the operation.  This will block the
whole tests.  PHDF5 is not using either features.  So, removed
them from the default tests.


Platforms tested:
Only in eirene using pp.  Copper is still down.
