new rules_pkg versions break distroless cacerts_java

[cristifalcas]

We are using cacerts_java internally and after upgrading to a newer version of rules_pkg, we saw that cacerts_java targets are broken now with this error:

every rule of type cacerts_java implicitly depends upon the target '@rules_pkg//:build_tar', but this target could not be found because of: no such target '@rules_pkg//:build_tar': target 'build_tar' not declared in package '' (did you mean 'BUILD'?) defined by

I believe it fails because of this: https://github.com/bazelbuild/rules_pkg/blob/main/CHANGELOG.md#internal-changes-1

It works with older versions: <= 0.4.0

I mean you could just copy those helpers over into here.
