The ftracetest script is a fairly complete test framework for tracefs-like
subsystem, but it can only be used for ftrace selftests.
If OPT_TEST_DIR is provided and includes a function file, use that as
test directory going forward rather than just grabbing tests from it.
Generalise function names like initialize_ftrace to initialize_system.
Add the --rv argument to set up the test for rv, basically changing the
trace directory to $TRACING_DIR/rv and displaying an error if that
cannot be found.
This prepares for rv selftests inclusion.

Fix mount_options.tc to use remount option to mount the tracefs.
Since the current implementation does not umount the tracefs,
this test always fails because of -EBUSY error.
Using remount option will allow us to change the mount option.

Add a selftest to check that the tracefs gid mount option is applied
correctly.
./ftracetest test.d/00basic/mount_options.tc
Use the new readme string "[gid=<gid>] as a requirement and also update
test_ownership.tc requirements to use this.
