34d8a498c4 Unbreak hyperlinks broken by go mod v2 conversion
Commit

  69d88505fd go mod: declare module version v2

translated all instances of "github.com/rfjakob/gocryptfs/" to
"github.com/rfjakob/gocryptfs/v2/".

Unfortunately, this included hyperlinks.

Unbreak the hyperlinks like this:

69d88505fd go mod: declare module version v2
Our git version is v2+ for some time now, but go.mod
still declared v1. Hopefully making both match makes
https://pkg.go.dev/github.com/rfjakob/gocryptfs/v2 work.

All the import paths have been fixed like this:

  find . -name \*.go | xargs sed -i s%github.com/rfjakob/gocryptfs/%github.com/rfjakob/gocryptfs/v2/%

98f735ff6e tests: drop "-z" from fusermount to catch forgotten fds

If the unmount fails, run "lsof" to find the open file.

Also fix the first bug we found this way.
