perf trace: Sample timestamp and cpu when using record flag

Sample timestamp and cpu just like the -R option.

Before:
            init-0     [-01] 1266874889.17179869184709551615: irq_handler_entry: irq=18 handler=eth0
            init-0     [-01] 1266874889.17179869184709551615: irq_handler_entry: irq=18 handler=eth0
            init-0     [-01] 1266874889.17179869184709551615: irq_handler_entry: irq=1 handler=i8042
            init-0     [-01] 1266874889.17179869184709551615: irq_handler_entry: irq=18 handler=eth0
            init-0     [-01] 1266874889.17179869184709551615: irq_handler_entry: irq=1 handler=i8042

After:
            init-0     [001]  7364.568965353: irq_handler_entry: irq=18 handler=eth0
            init-0     [001]  7365.530226877: irq_handler_entry: irq=1 handler=i8042
            init-0     [001]  7365.542831563: irq_handler_entry: irq=18 handler=eth0
            init-0     [001]  7365.644156299: irq_handler_entry: irq=18 handler=eth0
            init-0     [001]  7365.694556201: irq_handler_entry: irq=18 handler=eth0
