[petsc-dev] builds of PETSc based packages should not get their own secret files

And if we continue with the current model more and more "artifacts" won't exist unless we add them (and we will forget to add them).   I am fine with the output being in configure.log (as is the case for configures on external packages) or in make.log, it doesn't have to be in the CI console window, but it can't be scattered in dozens of files. 

We've never saved config.log [or equivalent] for all externalpackages [build either during configure or after petsc]

Currently we just save the build logs [to either configure.log - for packages that are built during configure, or to PETSC_ARCH/lib/petsc/conf - for packages that are built after petsc.

If we can add config.log [or equivalent] for  all externalpackages to some log file - or to PETSC_ARCH/lib/petsc/conf - that would be fine [and can be added to artifacts].

[currently make.log equivalent that we dump into configure.log is a bad format - stdout and stderr separated - so hard to co-relate errors to the commands invoked]


BTW: One of the reasons we had separate petsc4py.log and slepc.py  log was  we wanted make.log clean for our users - so that the commands we recommend [for subsequent steps] are not easily ignored.

[anything on stdout for CI will also be on stdout for users]

Generally the packages are relatively small and don't have a huge amount of output when compiling correctly.  I did it for PETSc4py and SLEPc (slepc4py is a mystery yet how it get's hidden in slepc).
