linux: Add support for custom license files

Browse Source 
The Linux package was not providing any license file when a custom
Linux version was selected.

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

[Arnout: use a single Kconfig option with conditional prompt]
