Add a series of tests to validate the RV tracefs API and basic
functionality.

* available monitors:
    Check that all monitors (from the monitors folder) appear as
    available and have a description. Works with nested monitors.

* enable/disable:
    Enable and disable all monitors and validate both the enabled file
    and the enabled_monitors. Check that enabling container monitors
    enables all nested monitors.

* reactors:
    Set all reactors and validate the setting, also for nested monitors.

* wwnr with printk:
    wwnr is broken on purpose, run it with a load and check that the
    printk reactor works. Also validate disabling reacting_on or
    monitoring_on prevents reactions.

These tests use the ftracetest suite. The first patch of the series
adapts ftracetest to make this possible.

The enable/disable test cannot pass on upstream without the application
of the fix in [1].
