perf trace requires root because it needs to use [ku]probes.
Skip those test when it's not run as root.

Before:
  $ perf test probe
   47: Probe SDT events                                                : Ok
  104: test perf probe of function from different CU                   : FAILED!
  115: perftool-testsuite_probe                                        : FAILED!
  117: Add vfs_getname probe to get syscall args filenames             : FAILED!
  118: probe libc's inet_pton & backtrace it with ping                 : FAILED!
  119: Use vfs_getname probe to get syscall args filenames             : FAILED!

After:
  $ perf test probe
   47: Probe SDT events                                                : Ok
  104: test perf probe of function from different CU                   : Skip
  115: perftool-testsuite_probe                                        : Skip
  117: Add vfs_getname probe to get syscall args filenames             : Skip
  118: probe libc's inet_pton & backtrace it with ping                 : Skip
  119: Use vfs_getname probe to get syscall args filenames             : Skip

Probes are global and other probe tests are already exclusive. These
two tests can throw warnings when run at the same time so mark them as
exclusive too:

  $ perf test -vvv 81 79

  79: perftool-testsuite_probe:
  --- start ---
  test child forked, pid 46419
  ../common/init.sh: line 137: /sys/kernel/debug/tracing/uprobe_events: Device or resource busy

Add new perf probe test case that acts as an entry element in perf test
list. Runs multiple subtests from directory "base_probe", which will be
added in incomming patches and can be expanded without further editing.
