internal/scan: improve error message for govulncheck

- Previously, an error was not returned if the govulncheck function was
  called without any patterns.
- Now if patterns are not included, then an explicit error is returned
  indicating to users that they should specify patterns or simply use
  `govulncheck ./...`.

Fixes golang/go#77167

Go Vulnerability Management

Go Reference

Go's support for vulnerability management includes tooling for analyzing your codebase and binaries to surface known vulnerabilities in your dependencies. This tooling is backed by the Go vulnerability database, which is curated by the Go security team. Go’s tooling reduces noise in your results by only surfacing vulnerabilities in functions that your code is actually calling.

You can install the latest version of govulncheck using go install

go install golang.org/x/vuln/cmd/govulncheck@latest

Then, run govulncheck inside your module:

govulncheck ./...

See the govulncheck tutorial to get started, and https://go.dev/security/vuln for more information about Go's support for vulnerability management. The API documentation can be found at https://pkg.go.dev/golang.org/x/vuln/scan.
