[PATCH v1 09/10] selftests/tdx: Compile with -D_GNU_SOURCE

[Edward Liaw <edliaw@xxxxxxxxxx>]

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.

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