perf test: Skip perf probe tests when running as non-root
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
