Masami Hiramatsu 6ee64cc302 fprobe: Add sample program for fprobe
Add a sample program for the fprobe. The sample_fprobe puts a fprobe on
kernel_clone() by default. This dump stack and some called address info
at the function entry and exit.

The sample_fprobe.ko gets 2 parameters.
- symbol: you can specify the comma separated symbols or wildcard symbol
  pattern (in this case you can not use comma)
- stackdump: a bool value to enable or disable stack dump in the fprobe
  handler.
