perf report: Show all sort keys in help output
Show all the supported sort keys in the command line help output, so
that it's not needed to refer to the manpage.
Before:
% perf report -h
...
-s, --sort <key[,key2...]>
sort by key(s): pid, comm, dso, symbol, parent, cpu, srcline, ... Please refer the man page for the complete list.
After:
% perf report -h
...
-s, --sort <key[,key2...]>
sort by key(s): overhead overhead_sys overhead_us overhead_guest_sys overhead_guest_us overhead_children sample period pid comm dso symbol parent cpu ...
