selftest/bpf: Test a perf BPF program that suppresses side effects
The test sets a hardware breakpoint and uses a BPF program to suppress the
side effects of a perf event sample, including I/O availability signals,
SIGTRAPs, and decrementing the event counter limit, if the IP matches the
expected value. Then the function with the breakpoint is executed multiple
times to test that all effects behave as expected.
