[PATCH v2 7/9] trace: fix metadata dump

[David Marchand <david.marchand@redhat.com>]

The API does not describe that metadata dump is conditioned to enabling
any trace points.

While at it, merge dump unit tests into the generic trace_autotest to
enhance coverage.

Fixes: f6b2d65dcd5d ("trace: implement debug dump")
Cc: stable@dpdk.org
