[OE-core][PATCH] iproute2: Make it easier to manipulate SUBDIRS list from bbappend

["Anatol Belski" <anbelski@linux.microsoft.com>]

Currently there's no easy way to override this part as it's hardcoded
into the EXTRA_OEMAKE var. This change makes it possible to manipulate
the list of subdirs in a more fine graned and future oriented manner.
