kselftest/alsa: Ensure _GNU_SOURCE is defined

Browse Source 
[ Upstream commit 2032e61e24fe9fe55d6c7a34fb5506c911b3e280 ]

The pcmtest driver tests use the kselftest harness which requires that
_GNU_SOURCE is defined but nothing causes it to be defined.  Since the
KHDR_INCLUDES Makefile variable has had the required define added let's
use that, this should provide some futureproofing.
