[PATCH v3 12/21] backports: make kconfig src_line backport / ConfigTree specific

["Luis R. Rodriguez" <mcgrof@do-not-panic.com>]

From: "Luis R. Rodriguez" <mcgrof@suse.com>

The kconfig source line used on a backport project is very
project specific. For backport packaging the source line simply
should follow the full path of the project but for integration
this will vary depending on the backport prefix directory used.
We'll add support for that next.
