[meta-intel] [master & fido][PATCH 05/16] meta-isg: dpdk: add external kernel module build handling for tmp/work-shared

[Ong Boon Leong]

DPDK software builds external kernel modules igb_uio.ko, rte_kni.ko & etc that
depend on the availability of kernel source. With splitting of kernel source
and artifacts into separate fodlers under tmp/work-shared, we need to handle
this by introducing do_configure[depends] += "virtual/kernel:do_shared_workdir"
to ensure build dependency is satisfied.

Refer to poky 46cdaf1 kernel: move source and build output to work-shared

This patch also introduces RTE_KERNELDIR_OUT variable to be used to setup
the kernel build artifact path. RTE_KERNELDIR remains as the kernel source path.
