Ismail Khoffi 8ae3334423 [libs/autofile & db/fsdb] Throw error if file permissions change (#2286)
* Enforce file permissions in case they've changed

* test behaviour for autofile

* use testify in tests and rename `fInf` to `fileInfo`

* return an error if file permissions have changed

- if we can't read the file, we'll still panic

* get rid of "github.com/pkg/errors" dependency

* address review comments:

- prefix instead of suffix
- add state to err and construct formatting in Error() method

* address review comments:

- move error to libs/errors
