Update Automake minimum version to 1.13.4

The embedded PMIx Automake minimum version is already 1.13.4, so to
autogen.pl Open MPI successfully, you already have to have Autoamek
1.13.4.  So we might as well make it official (i.e., bump Open MPI's
Automake minimum to match the Automake minimum in the embedded PMIx).
