[Buildroot] [PATCH v2 2/7] uboot: Add support for custom license files

[Kory Maincent]

The U-Boot 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.

Change in v2:
- Do not show license option if it is not a custom repo
