[Buildroot] [PATCH v2] linux: Fix URL for release candidate versions

[Luis Araneda <luaraneda@gmail.com>]

Starting with 4.12-rc1, tarballs are generated by cgit
directly from Linus's tree.
Also, set LINUX_SOURCE only on non-rc kernels,
and use <PKG>_SOURCE otherwise.

This method also applies to older release candidates.

  - Set LINUX_SOURCE only on non-rc kernels (suggested by Arnout)
