[patchlet] perf_counter tools: add --input=file option to builtin-sched.c

perf_counter tools: add --input=file option to builtin-sched.c.

perf sched record passes unparsed args on to perf record, so specifying an output
file via perf sched record -o FILE (cmd) just works.  Ergo, provide an option to
specify input file as well.

Also add the missing 'map' command to help.

Indeed, that's very useful when one keeps older (or different) traces 
around, renamed from perf.data to something else. It basically pushes 
the file based 'perf session' concept to perf sched as well.

Applied your fixes/enhancements to tip:perfcounters/core, thanks Mike!
