perf test: Allow skipping tests

Browse Source 
Sometimes a test is problematic for some reason and one wants to skip it,
for instance:

[root@sandy ~]# perf test
   1: vmlinux symtab matches kallsyms                        : Ok
   2: detect open syscall event                              : Ok
   3: detect open syscall event on all cpus                  : Ok
   4: read samples using the mmap interface                  : Ok
   5: parse events tests                                     :  Warning: bad op token {
    Warning: bad op token {
    Warning: bad op token {
    Warning: bad op token {
    Warning: bad op token {
    Warning: function is_writable_pte not defined
  Segmentation fault (core dumped)

So now we can use -s/--skip while the problematic tests are being fixed,
allowing us to test all the other entries:

  [root@sandy ~]# perf test -s 5
   1: vmlinux symtab matches kallsyms                        : Ok
   2: detect open syscall event                              : Ok
   3: detect open syscall event on all cpus                  : Ok
   4: read samples using the mmap interface                  : Ok
   5: parse events tests                                     : Skip (user override)
   6: x86 rdpmc test                                         : Ok
   7: Validate PERF_RECORD_* events & perf_sample fields     : Ok
   8: Test perf pmu format parsing                           : Ok
   9: Test dso data interface                                : Ok
  10: roundtrip evsel->name check                            : Ok
  11: Check parsing of sched tracepoints fields              : Ok
  12: Generate and check syscalls:sys_enter_open event fields: Ok
  13: struct perf_event_attr setup                           : Ok
  14: Test matching and linking mutliple hists               : Ok
  15: Try 'use perf' in python, checking link problems       : Ok
