[PATCH v3 67/68] selftests/wireguard: Drop define _GNU_SOURCE

[Edward Liaw <edliaw@xxxxxxxxxx>]

_GNU_SOURCE is provided by lib.mk, so it should be dropped to prevent
redefinition warnings.

Fixes: 809216233555 ("selftests/harness: remove use of LINE_MAX")
Signed-off-by: Edward Liaw <edliaw@xxxxxxxxxx>
