[0/4] Some RTLA fixes

Message

The first is a change in the Makefile to make rtla use the kernel
version.

The other fixes are in the error path when rtla fails to enable
the tracers. I got some segmentation faults when trying to use rtla
with kernel versions that do not support multiple instances (i.e.,
5.14 and 5.15) and fixed them. I also found some inconsistency in
error messages and also did a cleanup there.

Daniel Bristot de Oliveira (4):
  rtla: Follow kernel version
  rtla/utils: Fix session duration parsing
  rtla/trace: Error message fixup
  rtla/osnoise: Fix segmentation fault when failing to enable -t
