Merge pull request #45984 from cblecker/hack-vet

Automatic merge from submit-queue (batch tested with PRs 47921, 45984, 46829, 46896, 46923)

Move govet verify into rest of verify*-.sh scripts

**What this PR does / why we need it**:
Instead of having two govet scripts, consolidate them to into one and have both the Makefile and verify.sh scripts target the same script. This also will allow proper syntax highlighting and timing when the vet script is run as part of `make verify`.

**Which issue this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close that issue when PR gets merged)*: fixes https://github.com/kubernetes/test-infra/issues/2725

**Special notes for your reviewer**:

**Release note**:
