Arnaldo Carvalho de Melo e498f336d6 perf test shell: Add test using vfs_getname + 'perf trace' 
Uses the 'perf test shell' library to add probe:vfs_getname to the
system then use it with 'perf trace' using 'touch' to write to a temp
file, then checks that that was captured by the vfs_getname was used by
'perf trace', that already handles "probe:vfs_getname" if present, and
used in the "open" syscall "filename" argument beautifier.

Testing it:

  # perf test "trace + vfs_getname"
  61: Check open filename arg using perf trace + vfs_getname: Ok
  #

  # perf test -v "trace + vfs_getname"
  61: Check open filename arg using perf trace + vfs_getname:
  --- start ---
  test child forked, pid 30846
  Added new event:
    probe:vfs_getname    (on getname_flags:72 with pathname=result->name:string)

  You can now use it in all perf tools, such as:

  	perf record -e probe:vfs_getname -aR sleep 1

       2.237 ( 0.012 ms): touch/30855 open(filename: /tmp/temporary_file.kmoWQ, flags: CREAT|NOCTTY|NONBLOCK|WRONLY, mode: IRUGO|IWUGO) = 3
  test child finished with 0
  ---- end ----
  Check open filename arg using perf trace + vfs_getname: Ok
