linux-yocto_virtualization.inc: If using externalsrc adjust dependency

Browse Source 
When using externalsrc, the system will disable a number of tasks such as
do_validate_branches, do_unpack and do_patch.  The do_kernel_metadata task
is configured to run after do_validate_branches do_unpack and before
do_patch.  Since all of these have been removed, the task will never
run.

The do_kernel_metadata task is responsible for populating the
recipe-sysroot-native/kcfg directory via it's own dependency to
yocto-cfg-fragments-native:do_populate_sysroot.

Without do_kernel_metadata running, do_kernel_configme will fail to run
with errors like:
  ERROR: linux-xlnx-6.6.40+git-r0 do_kernel_configme: Feature '../recipe-sysroot-native/kcfg/cfg/virtio.scc' not found, this will cause configuration failures.
  ERROR: linux-xlnx-6.6.40+git-r0 do_kernel_configme: Check the SRC_URI for meta-data repositories or directories that may be missing
  ERROR: linux-xlnx-6.6.40+git-r0 do_kernel_configme: Set KERNEL_DANGLING_FEATURES_WARN_ONLY to ignore this issue

Fix this issue by detecting if we're running with externalsrc, and then
adding the task do_kernel_metadata (from the current recipe) as a
dependency of do_kernel_configme.

To reproduce th original issue:

  $ . ./oe-initbuild-env
  $ bitbake linux-yocto -c patch
  $ cp -r tmp/work-shared/<machine>/kernel-source linux-yocto

  edit the conf/local.conf adding:
  DISTRO_FEATURES:append = " virtualization"
  INHERIT += "externalsrc"
  EXTERNALSRC:pn-linux-yocto = "${TOPDIR}/linux-yocto"

  $ rm -rf tmp
  $ bitbake linux-yocto -c menuconfig
