ittnotify_static.c is not complaint with -Wundef compile option

[dzarukin]

$ gcc -Iinclude -Wundef -c src/ittnotify/ittnotify_static.c -o ittnotify_static.o
src/ittnotify/ittnotify_static.c:65:37: warning: "__INTEL_COMPILER" is not defined, evaluates to 0 [-Wundef]
 #elif HAS_GNU_ATTR(fallthrough) && !__INTEL_COMPILER
                                     ^~~~~~~~~~~~~~~~

The solution:

diff --git a/src/ittnotify/ittnotify_static.c b/src/ittnotify/ittnotify_static.c
index 17c50a5..5e6a0ea 100644

Hi @eparshut, I don't mind if the team handles it. But I can try to handle it, too, if you could share the process, please. The repo didn't let me create a branch to open a PR. I haven't try the fork though. Than you.

Looks like we need to add information to the readme on how to contribute to this repository.
