Tracing tooling updates for 6.8-rc4

Browse source 
RTLA:
         - rtla tools are exiting with a positive value when usage()
           is called. Make them return 0 if the usage was called via
           -h/--help.
 
         - the -P priority sets the sched priority for rtla workload.
           When the SCHED_OTHER scheduler is selected, it sets
           the rt_priority instead of the nice parameter. Setting
           the nice value is the correct thing, so fix it.
 
         - rtla is failing to compile with clang due to unsupported
           options from gcc. Adjusting the compiler/linker options
           makes clang work properly.
 
         - Remove the sched_getattr() unused function on utils.c.
 
         - Fixes on variable initialization and size, reported by
           clang.
 
 Verification:
         - rv is failing to compile with clang due to unsupported
           options from gcc. Adjusting the compiler/linker options
           makes clang work properly.
 
         - Fix an uninitialized variable on in_kernel.c reported by
           clang.
