perf trace record: handle commands correctly
Because the perf-trace shell scripts hard-coded the use of the
perf-record system-wide param, a perf trace record session was always
system wide, even if it was given a command.
If given a command, perf trace record now only records the events for
the command, as users expect.
If no command is given, or if the '-a' option is used, the recorded
events are system-wide, as before.
