devtools: fix tracepoint symbols check

The tracepoint symbols __rte_*_trace_* are defined via a macro,
adding prefix "__", so they cannot be found by map checker.
Those symbols defined by RTE_TRACE_POINT and RTE_TRACE_POINT_FP
are checked in source code without the generated prefix.

The same logic is applied to per core variables, previously skipped.
