petsc4py: conf: make dest_dir a parameter

This is is required for slepc4py, which derives a class from
PetscConfig. DESTDIR for PETSc (already built and installed) must be
distinct from DESTDIR for SLEPc (currently being built), hence the
path cannot come from the environment variable unconditionally.

petsc4py: build against the PETSc being built

Fixes Issue 862:

./configure --with-petsc4py=1 && make && make install DESTDIR=foo
<error>

Prior to this patch, when the Python extension is built against
the PETSc installed in the system, i.e. PETSc needs to be fully
installed before the extension can be built. This is a problem
for packaging recipes that want to use `--with-petsc4py=1` but
won't have PETSc installed into the system at the time the
one single top-level build gets to building the Python extension.

This patch allows petsc4py to be built against PETSc located
in the staging directory (DESTDIR). This involves four actions:

1. set PETSC_DIR the DESTDIR/PREFIX

2. but still pass DESTDIR to petsc4py build code (for items 3, 4)

3. input paths read from PETSc config files point into the final
installation location of PETSc, so need to be prepended with DESTDIR

4. output paths to be used after installation need to be stripped
of DESTDIR (they contain DESTDIR because of item 1)

NOTE: DESTDIR passed to the top-level makefile must be an absolute path.
A relative path would not resolve intuitively at the time of building
petsc4py, since the working directory would be `src/binding/petsc4py`.
