Options file processing: don't allow directories to be passed

Running something like

cd src/ksp/ksp/examples/tutorials
make ex1
mkdir foo
./ex1 -options_file foo

results in undesired behavior. In an OS X test it produced a "bus
error" and in a test on Ubuntu it hung in Petscgetline.

This commit assumes that PetscTestDirectory will always work,
checking if the supplied options file is a directory, and
producing an error iff the "require" flag is set.
