We don't use os.makedirs(dir, exist_ok=True) as that is too strict: it fails if
the directory already exists with different permissions (e. g. with 775). Thus
introduce a helper function ensuredir().
Add some "no cover" to some unrecoverable exceptions
(e.g. misconfiguration) or base-class methods that are not intended to
be invoked.

doop_source never (no longer?) creates an element in "virtual" where
the package name is prefixed with "-", so we can drop that branch.

The doop_source method does not generate any /binary/ undo items,
where the package name starts with "-". This fact allows us to remove
a branch in the undo code. This also happens to be fortunate because
the call to "inst_tester.remove_testing_binary" in that branch happens
to be wrong.

As a side effect, remove mips64el from NEW_ARCHES as we no longer need
that as a work around.
