support/scripts/br2-external: add kernel extensions

Browse Source 
Buildroot documentation section 9.2.1.6 "Additional kernel extensions"
indicates support for kernel extensions defined in external buildroot
trees but unfortunately, there didn't seem to be any support in
br2-external script.

This patch copies 'init' code support to include external kernel
extensions defined in 'linux' dir at the br2-external root directory as
explained in documentation.
