[PATCH 39/39] Compile tst-deadline.c with -Wno-ignored-attributes for Clang

[H.J. Lu]

Since tst-deadline.c is an internal test, compile tst-deadline.c with
-Wno-ignored-attributes for Clang to silence -Werror,-Wunknown-attributes
errors.  Also suppress -Wmaybe-uninitialized only for GCC in net-internal.h.
