Subject: -speed: print cpu model

When somebody posts "gocryptfs -speed" results, they are
most helpful together with the CPU model. Add the cpu model
to the output.

Example:

$ ./gocryptfs -speed
gocryptfs v2.2.0-beta1-5-g52b0444-dirty; go-fuse v2.1.1-0.20210825171523-3ab5d95a30ae; 2021-09-14 go1.17.1 linux/amd64
cpu: Intel(R) Core(TM) i5-3470 CPU @ 3.20GHz; with AES acceleration
AES-GCM-256-OpenSSL       	 862.79 MB/s
AES-GCM-256-Go            	 997.71 MB/s	(selected in auto mode)
AES-SIV-512-Go            	 159.58 MB/s
XChaCha20-Poly1305-OpenSSL	 729.65 MB/s
XChaCha20-Poly1305-Go     	 843.97 MB/s	(selected in auto mode)
