2a61261a5a hostinfo: use Uname from golang.org/x/sys/unix in osVersionLinux 
As already done in osVersionFreebsd. This will allow to use the Utsname
fields as []byte for easier conversion to string.

58a6c9b2b8 version, hostinfo: recognize gokrazy as a distro 
Now:

/tmp/breakglass3929186798 # /user/tailscale debug hostinfo
{
  "IPNVersion": "1.23.0-date.20220107",
  "OS": "linux",
  "OSVersion": "Gokrazy; kernel=5.16.11",
  "DeviceModel": "Raspberry Pi 4 Model B Rev 1.2",
  "Hostname": "gokrazy",
  "GoArch": "arm64"
}

Also, cache the distro lookup. It doesn't change while the program is
running:
