linux-yocto: fix race between checkout and meta data generation

There are two tasks that must run before a linux-yocto kernel is built.

  - Kernel checkout and relocation to work-shared (kernel_checkout)
  - Meta data gathering and configuration prep (kernel_metadata)

The current task definitions for both are simply "before do_patch",
which is correct, but kernel_checkout must run before and not race with
kernel_metadata.

So we set the definition of kernel_checkout to be more specific and
enforce the proper ordering.
