Change rationale for manually looking for CcInfo

We have to skip targets not providing CcInfo not just because of
incompatible targets in old Bazel versions, but also due to bug:
bazelbuild/bazel#19609

Given incompatible targets for aspects have been fixed in recent Bazel
versions and the bug above has just been discovered, it makes no sense
to keep mentioning incompatible targets as when above bug is fixed and we
can remove this manual check for CcInfo incompatible targets are no longer
relevant either way.
