simpleperf: Add --kprobe option in the stat command
It adds temporary kprobe events during stating.
Also add a shortcut in the stat command for creating
function entry kprobe events without arguments.
For example, we can use "-e kprobes:do_sys_openat2"
without --kprobe, to create a kprobe event monitoring
function entry of do_sys_openat2.
Also modify ProbeEvents's interface to reduce duplication.
Also use do_sys_openat2 instead of do_sys_open.
