cmd/cue/cmd: use testscript for top level command testing

This makes the command tests much more end to end,
and bundles test parameters together with the
test file dependencies.

We also make the actual main function more minimal
to avoid duplicating it inside TestScript, and fix the
code so that it prints errors to standard error and
avoids printing the "terminating because of errors"
sentinel error value.

The test coverage is somewhat improved as a result.
