chore: exclude yardstick store from filename rules

[willmurphyscode]

Enables "make lint" to be run after "make quality". Previously, the linter rules that prohibit ":" in any filename would fail if the yardstick or vulnerability-match-labels directories had been initialized (e.g. if "make quality" had been run), since they have filenames like "sha256:abcd" in them. Exclude them from this lint, since they are not go files.

Manual testing done

Test case where repo has yardstick state, and thus files with ":":

1. Run make in test/quality to get some yardstick state in the workspace
2. Prove that there are a lot of files with : in the name: find . | grep -e ":" | wc -l prints ~17k.
3. Run make lint from the root of this workspace; it succeeds.

Running make lint on main, before this change, if the yardstick state is initialized, fails like this:

❯ make lint
Running linters
# ensure there are no go fmt differences
files with gofmt issues: []
# run all golangci-lint rules
./.tmp/golangci-lint run --tests=false
# go tooling does not play well with certain filename characters, ensure the common cases don't result in future "go get" failures
make: /bin/sh: Argument list too long
make: *** [lint] Error 1

Test case where this state hasn't existed (to make sure the subshell exiting differently because of the grep or whatever doesn't break something):

git clone -b ignore-label-and-image-dirs git@github.com:anchore/grype grype-test && cd grype-test && make bootstrap && make lint

exits zero.
