perf record: Add '--timestamp-filename' option to append timestamp to output file name
This option appends current timestamp to the output file name.
For example:
# perf record -a --timestamp-filename
^C[ perf record: Woken up 1 times to write data ]
[ perf record: Dump perf.data.2015122622265847 ]
[ perf record: Captured and wrote 0.742 MB perf.data.<timestamp> (90 samples) ]
# ls
perf.data.201512262226584
The timestamp will be useful for identifying each perf.data after the
'perf record' support for generating multiple output files gets
introduced.
