gofmt: support rewrite

[trim21]

close #3171

need to merge golangci/gofmt#2 first and update gofmt in go.mod

example:

$ go run .\cmd\golangci-lint\main.go run --disable-all -E=gofmt --gofmt.rewrite='interface{} -> any'
pkg\fsutils\filecache.go:59: File is not `gofmt`-ed with `-s -r "interface{} -> any"` (gofmt)
        fc.files.Range(func(_, fileBytes interface{}) bool {
internal\errorutil\errors.go:9: File is not `gofmt`-ed with `-s -r "interface{} -> any"` (gofmt)
        recovered interface{}
pkg\report\log.go:23: File is not `gofmt`-ed with `-s -r "interface{} -> any"` (gofmt)
func (lw LogWrapper) Fatalf(format string, args ...interface{}) {
exit status 1

golangci.yaml

  gofmt:
    simplify: true
    rewrite: 'interface{} -> any'
