Subject: Fix issue with reverse mode and excluded virtual files

This fixes #686. Now the `gocryptfs.longname.*.name` are present and readable in the
reverse mount, regardless of the complexity of the exclusion patterns.

The main issue was a `cPath` instead of `dPath` for the exclude check in
`fusefrontend_reverse/node_helpers.go`. Also added a check to avoid the exclusion of
`gocryptfs.conf` in the root directory.

The test run results are in line with the main branch.

Fixes https://github.com/rfjakob/gocryptfs/issues/686
