perf bench breakpoint: Skip run if no breakpoints available
Based on commit 7d54a4acd8c1de3e ("perf test: Skip watchpoint tests if
no watchpoints available"), hardware breakpoints are not available for
power9 platform and because of that 'perf bench breakpoint' run fails on
power9 platform.
Add code to check for the return value of perf_event_open() in the
breakpoint run and skip the 'perf bench breakpoint' run, if hardware
breakpoints are not available.
Result on power9 system before patch changes:
[command]# perf bench breakpoint thread
perf_event_open: No such device
Result on power9 system after patch changes:
[command]# ./perf bench breakpoint thread
Skipping perf bench breakpoint thread: No hardware support
