bug(scan): --file-patterns doesn't work for some post-analyzers

[DmitriyLewen]

Description

In most post-analyzers we use required function in PostAnalyze.

trivy/pkg/fanal/analyzer/language/nodejs/npm/npm.go

Lines 49 to 51 in 3eecfc6

	required := func(path string, _ fs.DirEntry) bool {
	return filepath.Base(path) == types.NpmPkgLock
	}

But we don't have info about file-patterns in PostAnalyze function.
That is why --file-patterns flag may not work.

We need to update our logic to take into account file-patterns for PostAnalyze
