trace, documentation: Fix branch profiling location in debugfs
The debugfs interface for branch profiling is through
/sys/kernel/debug/tracing/trace_stat/branch_annotated
/sys/kernel/debug/tracing/trace_stat/branch_all
so update the Kconfig accordingly.

This tracer profiles all the the likely and unlikely macros
in the kernel. It will display the results in:
- /sys/kernel/debug/tracing/profile_annotated_branch
+ /sys/kernel/debug/tracing/trace_stat/branch_annotated
Note: this will add a significant overhead; only turn this
on if you need to profile the system's use of these macros.
