[PATCH v2 2/5] selftests/sgx: Include KHDR_INCLUDES in Makefile

[Edward Liaw]

Add KHDR_INCLUDES to the CFLAGS to pull in the kselftest harness
dependencies (-D_GNU_SOURCE).

Also, remove redefinitions of _GNU_SOURCE in the source code.

Fixes: 809216233555 ("selftests/harness: remove use of LINE_MAX")
