etherwake: add missing lincense information

[feckert]

Maintainer: @neheb @tripolar Compile tested: not needed Run tested: not needed

Description:

In the source there is a note that it is under GPL. But it is not clear which version of the GPL (GPL-1.0, GPL-2.0, GPL-3.0).

At the time the source file was created, GPL-2.0 was the latest GPL. Also, in debian the package refers to GPL which is a symlink to GPL-3.0.

Therefore the PKG_LICENSE variable is set to GPL-2.0-or-later.

If we are not sure about this, just reach upstream developers.

Hello Mr. Donald Becker,

As you may know, the source of your written ether-wake tool
is used in various distributions. This is also the case for
OpenWrt.I am currently in the process of adding the missing
licenses tags in the OpenWrt buildsystem for tools the does
not have a valid PKG_LICENSE variable set in the build
Makefile[[1](https://github.com/openwrt/packages/pull/23705)].

This also applies to your source of the etherwake package [[2](https://git.openwrt.org/?p=feed/packages.git;a=blob;f=net/etherwake/Makefile;hb=HEAD)]
that compiles your source in OpenWrt.

In the source file it says that it is GPL but not exactly
which one.

I think we have the following to choose for GPL that are eligible [[3](https://spdx.org/licenses/)]
* GPL-1.0-only
* GPL-1.0-or-later
* GPL-2.0-only
* GPL-2.0-or-later
* GPL-3.0-only
* GPL-3.0-or-later

Thank you for your feedback.

Best regards

Florian
