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

[Mike Galbraith <efault@gmx.de>]

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.
