selftests: Compile kselftest headers with -D_GNU_SOURCE
Add the -D_GNU_SOURCE flag to KHDR_INCLUDES so that it is defined in a
central location.
Commit 809216233555 ("selftests/harness: remove use of LINE_MAX")
introduced asprintf into kselftest_harness.h, which is a GNU extension
and needs _GNU_SOURCE to either be defined prior to including headers or
with the -D_GNU_SOURCE flag passed to the compiler.
