perf script: Improve error msg when no first/last sample time found

The following message will be returned to user when executing 'perf
script --time' if perf data file doesn't contain the first/last sample
time.

"HINT: no first/last sample time found in perf data.
 Please use latest perf binary to execute 'perf record'
 (if '--buildid-all' is enabled, needs to set '--timestamp-boundary')."
