Teach perf-record about the new perf_event_attr::{use_clockid, clockid}
fields. Add a simple parameter to set the clock (if any) to be used for
the events to be recorded into the data file.
Since we store the entire perf_event_attr in the EVENT_DESC section we
also already store the used clockid in the data file.

[ Conditionally define CLOCK_BOOTTIME, at least rhel6 doesn't have it - dsahern
Ditto for CLOCK_MONOTONIC_RAW, sles11sp2 doesn't have it - yunlong.song ]
