[PATCH] trace: fix metadata dump

[David Marchand]

[ upstream commit d4cbbee345e2ea1126f3f43cbc1fedaf1245feb0 ]

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")
