[bug#34647] [PATCH] gnu: python-petsc4py: Update to 10.3.1.

Thank you for doing the fenics test too.  

I have fixed the build problem for fenics-dolfin in patch #34668.

These patches for python-petsc4py and fenics-dolfin have been made 
necessary by the recent update of the PETSc dependency.  Essentially,
a symbol that used to be referenced in these packages is no longer
made available by PETSc.

Best regards,

Paul.
