Remove test/chpldoc.skipif

There are two reasons to do this: first, the adjustments which made chpldoc
testing happen on tests with .doc in their names caused skipping those tests
when chpldoc is not present to happen naturally; second, this skipif is not
working correctly as it relies on chpldoc living in our path, which is not the
case in nightly testing (chpl isn't in our path either).
