babeltrace2: Fix ptest execution in minimal images and add debug info

Tweak the ptest dependencies so they work correctly in minimal images. There
appears to be some usage of find or xargs that doesn't work with busybox.

Also improve the test runner so the test-suite.log is dumped upon error
which makes debugging much easier.
