linux-yocto: fix externalsrc builds

Richard/Saul,

This is a fix for externalsrc builds when the linux-yocto bbclass is used.

The commit tells most of the story:

-----

There are a few extra task that modify the source tree that should be removed when externalsrc is inherited by a recipe that uses a linux-yocto tree.

Adding those tasks to SRCTREECOVEREDTASKS means that they are skipped and externalsrc works as intended.

-----

You'll note that do_patch is repeated in SRCTREECOVEREDTASKS here, since my tested showed that only having it in externalsrc.bbclass did not inhibit the kernel-yocto.bbclass variant from running

There's no impact if externalsrc isn't being used, so this is a safe change (from where I stand :)

Cheers,

Bruce
