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.
