package/linux-headers: Add support for custom license files

Browse Source 
The linux-headers package was not providing any license file for any
version other than the latest one.

Fix this by adding a Kconfig option to specify the license file,
with a default value set to the commonly used license paths.

For the headers-as-kernel case, use LINUX_LICENSE_FILES and disable the
Kconfig option entirely.
