selftests/resctrl: Move _GNU_SOURCE define into Makefile
commit 3a1e4a91aa
upstream.
_GNU_SOURCE is defined in resctrl.h. Defining _GNU_SOURCE has a large
impact on what gets defined when including headers either before or
after it. This can result in compile failures if .c file decides to
include a standard header file before resctrl.h.
It is safer to define _GNU_SOURCE in Makefile so it is always defined
regardless of in which order includes are done.
