Arnaldo Carvalho de Melo 1ad5a18269 perf test shell: Check if 'perf probe' is available, skip tests if not 
Add a library function that checks if 'perf probe' is built into the
tool being tested, skipping tests that need it.

Testing it on a system after removing the library needed to build
'probe' as a perf subcommand:

  # perf test ping vfs_getname
  59: Use vfs_getname probe to get syscall args filenames   : Skip
  60: probe libc's inet_pton & backtrace it with ping       : Skip
  61: Check open filename arg using perf trace + vfs_getname: Skip
  62: Add vfs_getname probe to get syscall args filenames   : Skip
  # perf probe
  perf: 'probe' is not a perf-command. See 'perf --help'.
  #

Now reinstalling elfutils-libelf-devel on this Fedora 26 system to
rebuild perf and then retest this:

  # perf test ping vfs_getname
  60: Use vfs_getname probe to get syscall args filenames   : Ok
  61: probe libc's inet_pton & backtrace it with ping       : Ok
  62: Check open filename arg using perf trace + vfs_getname: Ok
  63: Add vfs_getname probe to get syscall args filenames   : Ok
