Commit 287050d39026 ("tracing: Add TRACE_EVENT_CONDITIONAL()") adds
macros to define conditional trace events (TRACE_EVENT_CONDITIONAL) and
tracepoints (DECLARE_TRACE_CONDITION), but sets up functionality for
direct use only for the former.
Any attempt to use DECLARE_TRACE_CONDITION fails the build.
Add preprocessor bits in define_trace.h to allow usage of
DECLARE_TRACE_CONDITION just like DECLARE_TRACE.
Fixes: 287050d39026 ("tracing: Add TRACE_EVENT_CONDITIONAL()")
