Automated rollback of commit bbe47a1.

*** Reason for rollback ***

Breaks Bazel's target //scripts/packages/debian:bazel-debian.deb which is needed for bazel releases.

*** Original change description ***

Disable outputs param of rule function

This constitutes an incompatible change guarded by flag --incompatible_no_rule_outputs_param. See bazelbuild#7977 for further details.

Implementation for bazelbuild#7977.

RELNOTES: The `outputs` parameter of the `rule()` function is deprecated and attached to flag `--incompatible_no_rule_outputs_param`. Migrate rules to use `OutputGroupInfo` or `attr.output` instead. See bazelbuild#7977 for more info.
