Will Norris 71029cea2d all: update copyright and license headers
This updates all source files to use a new standard header for copyright
and license declaration.  Notably, copyright no longer includes a date,
and we now use the standard SPDX-License-Identifier header.

This commit was done almost entirely mechanically with perl, and then
some minimal manual fixes.

Updates #6865

Brad Fitzpatrick 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:

name   old time/op    new time/op    delta
