[PATCH] kernel-devsrc: Ensure we don't race against do_make_scripts from module-base.bbclass

[Richard Purdie <richard.purdie@linuxfoundation.org>]

do_install for kernel-devsrc can race against do_make_scripts from 
module-base.bbclass. Since there is a lock there to guard against concurrency
already, we can just use it here to avoid a race.

Ultimately, this can all likely be much more streamlined but this resolves
the immediate build failures.
