            Install petsc/mpiuni headers for the --with-mpi=0 builds

Upstream installs the mpiuni headers exactly when the build uses MPIUni
(config/install.py, installIncludes):

    if not self.mpi.usingMPIUni:
      exclude.append('mpiuni')

This spec hand-copies the include tree rather than using upstream's
install target, and currently has that rule inverted: mpiuni is copied
into the two --with-mpi=1 flavours, which never use it, and omitted from
the two --with-mpi=0 flavours, which require it.

The result is that petscsys.h's

    #include <petsc/mpiuni/mpi.h>

cannot be satisfied, so no package can include a PETSc header against
petsc-devel or petsc64-devel. Seen as an FTBFS in getdp-3.6.0-17.fc46.
