kernel-yocto: allow kernel-meta repositories to be patched
For testing purposes, it is often easier to patch a fragment
in a kernel-meta repository versus needing to make a copy or
modify the source repository.
We can allow this sort of patching when a patchdir of kernel-meta
is passed (to indicate the nested kernel-meta repository).
Also note that we must patch the meta data before they are
processed/gathered, since migrated copies to the kernel source
directory will be used later.
