perf: sched map skips redundant lines with cpu filters

perf sched map supports cpu filter.
However, even with cpu filters active, any context switch currently
corresponds to a separate line.
As result, context switches on irrelevant cpus result to redundant lines,
which makes the output particlularly difficult to read on wide
architectures.

Fix it by skipping printing for irrelevant CPUs.

Example snippet of output before fix:

  *B0       1.461147 secs
   B0
   B0
   B0
  *G0       1.517139 secs

After fix:

  *B0       1.461147 secs
  *G0       1.517139 secs
