Supports analysis package error format in golangci-lint test

[sonatard]

In order to add a linter to golangci-lint, we need to add tests. However, the error format is different between the analysistest package and golangci-lint, so we have to change it. If same error format, we can reuse the test cases by simply copying test files.

golangci-lint test error format

http.Get(url) // ERROR "net/http.Get must not be called"

golangci-lint/test/testdata/noctx.go

Line 16 in 4fb9fe5

http.Get(url) // ERROR "net/http\.Get must not be called"

analysistest package error format

http.Get(url) // want net/http\.Get must not be called

Is there any reason for the different error formats?
