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.
