README: replace openssl-gcm.md with link to wiki

Browse Source 
The CPU-Benchmarks wiki page has a lot more info
than openssl-gcm.md had.

Go builtin GCM vs OpenSSL
=========================
OpenSSL is over four times faster than Go's built-in GCM implementation.
```
$ cd internal/stupidgcm
$ go test -bench .

and significantly faster than EncFS' "paranoia" mode that provides
a security level comparable to gocryptfs.
gocryptfs uses OpenSSL through a thin wrapper called `stupidgcm`.
On CPUs without AES-NI, gocryptfs uses OpenSSL through a thin wrapper called `stupidgcm`.
This provides a 4x speedup compared to Go's builtin AES-GCM
implementation - see [openssl-gcm.md](Documentation/openssl-gcm.md)

implementation. See [CPU-Benchmarks](https://github.com/rfjakob/gocryptfs/wiki/CPU-Benchmarks)
for details, or run `gocryptfs -speed` to see the encryption performance of your CPU.
Example for a CPU without AES-NI:
Run `./benchmark.bash` to run gocryptfs' canonical set of
```
$ ./gocryptfs -speed
AES-GCM-256-OpenSSL 165.67 MB/s (selected in auto mode)
AES-GCM-256-Go 49.62 MB/s
AES-SIV-512-Go 39.98 MB/s
```
You can run `./benchmark.bash` to run gocryptfs' canonical set of
benchmarks that include streaming write, extracting a linux kernel
tarball, recursively listing and finally deleting it. The output will
look like this:
