Subject: gocryptfs -speed: call testing.Init() to not panic

Looks like I should have been calling testing.Init()
all along. From https://pkg.go.dev/testing#Init :

> Init is only needed when calling functions such as
> Benchmark without using "go test".

Panic only affected without_openssl builds and looks
like this:

  $ ./gocryptfs -speed
  gocryptfs v2.4.0-2-g8b1c4b0-dirty without_openssl; go-fuse v2.3.0; 2023-09-15 go1.21.1 linux/amd64
  cpu: Intel(R) Core(TM) i5-6500 CPU @ 3.20GHz; with AES acceleration
  AES-GCM-256-OpenSSL             panic: runtime error: invalid memory address or nil pointer dereference
  [signal SIGSEGV: segmentation violation code=0x1 addr=0x0 pc=0x5a5d20]

  goroutine 7 [running]:
  testing.(*common).decorate(0x40d625?, {0xc00001c150, 0x2a}, 0x830601?)
          testing/testing.go:772 +0xa0
  [...]
