script add -T fmt to print time-stamps

2022-11-02T09:44:46Z

script -r is useful for recording time-stamps of when output happened. With -T, rather than playback the script in real-time we simply print the time-stamps to show when the output happened. This is very useful for example, for analyzing boot time activity. If the fmt provided contains no % characters the default %n@ %s [%Y-%m-%d %T] is used, which lends itself to analysis by tools as well as humans. Sponsored by: Juniper Networks, Inc.

(cherry picked from commit 7b45ad3f89cc4d65a23f7d034329dd3f8dd3105f) script: use %n at the end of default tstamp_fmt Since we are only outputting time-stamps when they differ ending it with a newline, interferes with the output less.
