examples: remove useless debug flags

The debug logs must be enabled at compile-time and run-time.
There are also some internal flags in some examples to enable the debug
logs of the applications. They are now enabled in debug configs and
can be disabled thanks to the more generic logtype mechanism:
	rte_set_log_type(RTE_LOGTYPE_USER1, 0);

Removing these #ifdef allows to test these code branches more easily
and avoid dead code pitfalls.
